Aurora Designs Accessories for Classic Car Radios

Aurora accessories are a must have for a classic radio upgrade, but keep in mind that aside from the Vbx-1 electronic vibrator, there is no direct sell of these products to the consumers. The other products listed are offered only if the customer sends their unit in for a professional installation.
The VBx-1 model of the electronic vibrator speaks to a radical new worldview in vibrator substitutions. Chip controlled for the most astounding precision and elements accessible, nothing else even approaches. But why is this such a breakthrough?

Before this innovation, mechanical vibrators used direct comparative toward those utilized as a part of ignition frameworks of more established autos. These focuses are liable to wear, setting, and oxidization. Strong State vibrators switch electrical current with transistors like present day vehicles ignition frameworks. While mechanical focuses have an existence of around 100 million operations, transistors can work dependably at 1 million operations for every second for quite a long time.

Mechanical vibrators got their name from the metal armature that vibrates in nearness to an electro-magnet to open and close the focuses. The HUM you hear when your radio is working is an immediate consequence of this activity. Strong State vibrators have no moving parts – they're totally quiet in operation.

With couple of special cases, mechanical vibrators have not been produced for over 30 years. The New-Old-Stock that remaining parts is influenced by maturing. A huge rate of NOS vibrators won't work legitimately because of oxidization of the focuses, and/or crumbling elastic that protects the instrument from the can. The Solid State vibrators in our index are cutting edge innovation, bundled in metal jars with base styles to precisely copy in structure, fit, and capacity about each sort of vibrator utilized as a part of US "plant" car radios since their creation in 1932. Vibrators are also made to fit most Becker, Blaupunkt and other European radios, and some Australian sorts.


Dissimilar to mechanical vibrators, Solid State vibrators are extremity delicate. The majority of our vibrators utilize an addition after the part number that assigns the vibrator for use in a Positive or Negative ground electrical framework. The Antique Automobile Radio Automobile Battery Grounding Chart demonstrates the correct ground extremity for all real US automakers from 1932-1957. On the off chance that you are not certain of your vehicle ground extremity, please check which terminal of your battery is associated straightforwardly to the motor piece or auto body.

A Solid State vibrator won't settle a something else "broke" radio. Nothing can make up for shorted cushion condensers, disintegrated electrolytic capacitors, or different illnesses regular to 40 or 50 year old radios. In the event that you need to attempt a Solid State vibrator on the grounds that mechanical vibrators keep wrecking in your radio, it would be a smart thought to first have the radio looked at for shorts in the B+ circuits. Dependable guideline: 6 volt radios ought to draw approx. 1 amp for every tube, not including the rectifier. 12-volt radios that utilization a vibrator ought to draw about ½ amp per tube barring the rectifier.

Whether you utilize a Solid State or mechanical vibrator, both the radio producer and the vibrator maker prescribe that you supplant the cushion condenser every time you supplant the vibrator. Note: In some synchronous vibrators, the cradle is incorporated with the vibrator.

Strong State vibrators can't be tried with an ohmmeter or with a customary vibrator analyzer. The majority of their parameters are tried amid and after production, and must meet demanding benchmarks. Field testing ought to be finished by introducing the vibrator in a radio known not in great working request, and of the correct extremity.

Try not to work your radio specifically from a battery charger. Never introduce a 6-volt radio in an auto with a 8-volt battery without a reducer. While the above practices most likely won't harm the vibrator, either can crush different parts of the radio in a brief time frame.
Full insurance against converse battery, shorted yields and over force, this model is about as indestructible as they come. Due to this toughness, the model can be directly wired into the circuit like some other hearty segment, for example capacitors and resistors. It can likewise be connected to a unique style vibrator platform for fitting capacity, or even put inside the jar of a unique vibrator. This adaptability allows the elusive pin vibrators (5, 6 & 7) to become a non-issue. Only a single board is necessary for all positive ground establishments and one for all negative ground establishments.

Using advanced calculations, the microchip permits the VBx-1 to present such unfathomable components as deadband activity, postponed begin, delicate begin, deferred restart, hamper and over force insurance, all with dumbfounding exactness. The deadband activity, postponed begin and delicate begin highlights specifically enormously diminish the weights on the rectifier and transformer augmenting their lives.

Does the vibrator ensure itself, as well as secures costly items in the unit like the rectifier, transformer and channels. Dissimilar to basic vibrators that will consume a transformer if something as straightforward as the cushion shorts in the capacitor, the VBx-1 instantly faculties this condition ensuring itself and the transformer till the cradle capacitor can be supplanted. No more can an imprudent client demolish costly parts in their radio just by abandoning it turned on after a disappointment.

Similarly, all Aurora Design items is intended to SAE details and implicit America at an autrhorized facility.

AUX-1 is a processor fueled by a supplementary stimulus controller that improves adding a sound contribution to unique units. It has 3 levers that can be utilized freely or as a part of any mix to change the unit over from typical activity to the helper information. The three triggers are a VOX, power cycling and a switch info. The VOX hardware and calculations depend on the prevalent VOX execution of the FMR-1 units. It is greatly delicate and to a great degree great at dismissing commotion. This outcomes in no changing back to the unit amid calm sound sections.

The sound yield from the this device is high to organize the output of tube radios. While clearly partner a MP3 units to the sound intensifier on some tube devices results in minimum volume and miserable execution, the digitally contained enhancer on this device successfully facilitates the output of any system.

Full security against inverse battery, the AUX-1 verges on indestructible. Through sharp edge arrange, this device is great with 6V/12V grounds (pos/neg) radios realizing one and just board being necessary for all foundations.

Aurora Design things have a couple simularities, the Vbx-1 and substitute things are planned to specific SAE points of interest. They are all verifiable America at an top level inspection foundation.

The HPC-1 offers another level of execution in 6V vehicles. As of recently, proprietors of vehicles with unique 6/12V positive ground and 6V negative ground frameworks were amazingly constrained with their changed over radios because of the sickly yield of accessible force converters. With the HPC-1, proprietors can now completely drive two 4 ohm speakers, or four speakers at diminished force.

The HPC-1's exceptionally proficient synchronous outline guarantees low power dissemination while giving most extreme yield to the radio. The HPC-1 can give up to 56W yield power from a 6V positive ground framework and 90W yield power from a 6V negative ground framework with the motor at quick sit still.

Completely sifted on all associations, and using exclusive EMI decrease hardware, the HPC-1 gives a to a great degree clean yield without the requirement for substantial, power looting outside channels.

The HPC-1 highlights full invert battery and transient insurance. A low voltage lockout circuit guarantees the converter dependably works appropriately. Not any more blown circuits or harmed converters because of a powerless battery! Because of the astute outline of the HPC-1, just a solitary board is required for all establishments decreasing stock. Its to a great degree little size and low EMI yield permit it to be mounted specifically inside the changed over radio improving establishment and operation.

Similarly as with all Aurora Design items, the HPC-1 is intended to SAE particulars and implicit the USA at an authorized ISO9001:2000 office.

The HPC-1 high power voltage converter is utilized as a part of conjunction with a FMR-1 AM/FM recipient in 6/12V positive ground or 6V negative ground establishments. By demonstrating ostensible yield force of 60W-92W, the FMR-1 can completely drive two 4 ohm speakers, or four speakers at diminished force. A solitary board is utilized for all establishments meaning less stock is required. Completely sifted on all associations, and using exclusive EMI lessening hardware, the HPC-1 requires no vast force victimizing outer channels yet still gives a to a great degree clean yield. There are four association cushions and two mounting gaps on the HPC-1 module. Since the module can disseminate ~8W of warmth under full load, it should be mounted to the undercarriage in the radio. The module ought to be mounted similarly as useful from the FMR-1, tuning instrument, BT-1 and recieving wire/connector. The leads from the module ought to likewise be directed far from the in advance of said gadgets. The two information cushions, VIN + and - acknowledge up to 14 gage wire while the two yield cushions, VOUT and GND acknowledge up to 16 gage wire. The GND cushion ought to associate with the radio suspension utilizing a short, overwhelming wire. The VOUT cushion interfaces with the Battery and Switched battery cushions on the FMR-1. The VIN - cushion (for negative ground establishments) or VIN + cushion (for positive ground establishments) is associated with the radio case with a short, overwhelming wire. The rest of the VIN cushion will turn into the battery include and is associated with the first power switch on the radio. The HPC-1 ought to be intertwined at 10A most extreme for positive ground establishments and 15A greatest for negative ground establishments. Cut the association prompts guarantee they won't short out to the radio skeleton when the unit is mounted. Apply warm oil to the aluminum slug on the back of the HPC-1 and secure it to the radio undercarriage utilizing the supplied equipment. Fix the #4-40 fastens to 5 lbs (0.5N-m). Don't over-fix the #4-40 screws as harm to the segments on the pcb could come about.
The FMR-HV1 is utilized to control the high voltage look for transfers utilized as a part of numerous late 1950's Delco® Wonderbar® radios. The FMR-HV1 is a present restricted supply that works with both the low impedance and high impedance style transfers. With it's 52V open circuit yield voltage, even the high impedance style transfers will work typically without weakening the arrival spring. Not at all like contending supplies that work at 20-40kHz bringing about clamor over the AM band, the FMR-HV1 utilizes a car exchanging controller working at 2MHz. Since this recurrence is over the AM band, the FMR-HV1 can't meddle with AM gathering.

The FMR-HV1 is completely independent and requires no outer parts. It is intended to wire straightforwardly between the FMR-1 and the look for transfer. It's ultra little size and high productivity permit it to be effectively mounted anyplace inside the radio.

Similarly as with all Aurora Design items, the FMR-HV1 is intended to SAE details and composed and worked in the USA at an ISO9001:2000 office.

The FMR-HV1 high voltage relay driver is used to operate the high voltage relays in the Delco® E-Series Wonderbar® and similar radios. Because the relays in these radios also control the spring motor mechanism, they are not easily replaced with low voltage relays. The FMR-HV1 uses an automotive regulator that operates at 2MHz. By placing the switching frequency above the AM band, no interference will occur. This switching frequency also allows the use of smaller components resulting in the extremely small size of the FMR-HV1. The Chassis Ground pad should be connected to the radio chassis using a short, heavy piece of wire. The Mounting Pad is supplied just to facilitate stable mounting of the pcb. It is not electrically connected. It should also be connected to the radio chassis with a short, heavy piece of wire. A switched battery source of 12V is connected to the Switched Battery pad. The grounding Seek output from the FMR-1 is connected to the RLY Pad. The two wires from the relay connect to the Relay Output pads. No diodes or other components should be used across the relay as the FMR-HV1 is fully protected for driving an inductive load and these components will interfere with it’s operation. More information can be found in the FMR-1 Installation Manual.
