There is some hash noise, but adding a choke, and modifying the buffer cap circuit a little bit can help eliminate that noise. Option B is try to rebuild a mechanical vibrator. It's not impossible, but it can be a real challenge, especially if the contacts are burnt. This vibrator is basically just a very basic solid state DC to DC conversion chopper circuit. The new mechanical vibrators could be almost as square wave noisy as these solid state replacements, sometimes even worse, complete with switch bouncing, overshoot, creating even worse noise. When I ran other 6 volt AM radios, in other old vehicles I owned, running the radio without the engine running was somewhere between inadvisable and incredibly stupid. Starting my 1947 GMC with an Airline Wards add on radio on would fry the ignition points. When I finally found the stock General Motors radio, same deal, start the truck with the radio on, and burn the points. These 6 volt radios draw 18-24 amps. You may as well leave the headlights on too, and schedule AAA to come and give you a jump start in two hours. I'd say a half hour, but Arizona's AAA service is really slow, and horrible. The way my oil pan was bolted to a giant flange on the engine block, I eventually just added a 12 volt alternator to the truck, mounted on angle iron. It just bolted on, so totally reversible! Just like modifying that silver face Fender amp, if you don't like it, change it again. Slopifying the buffer cap by using two caps totem poled with balancing resistors can smooth out some of that noise. SOME LATER VAC TUBE CAR RADIOS ACTUALLY USED TRANSISTOR CHOPPERS INSTEAD OF MECHANICAL VIBRATORS! MAYBE PAY A VISIT TO YOUR LOCAL LIBRARY AND LOOK UP SOME HOWARD SAM'S SCHEMATICS!

They are a fairly good replacement but I do have a problem with them. It seems that they don't perform well unless the supply voltage is well over 6 volts. In a typical setup, the car's voltage will go to about 7.5 volts when it is running and charging. The vibrator works well under these conditions. However when the voltage is around 6 volts or slightly less, it doesn't seem to work.

This vibrator generates a very square waveform that doesn't match that of the original mechanical type. The result is 115hz hash that gets picked up across the dial of the radio. Yes, this one will get you going but you will quickly learn to hate the high pitch whine picked up between strong stations.

The Radio in the Hudson Hornet is working again. I pilfered a really good 6V6 from it and put a Chinese one in it, but it is just an AM radio. Those old car radios were built like tanks too. Now I am pulling the preset knobs for some thorough ectro-cleaning, and some new tin plating. The rest of it is just aces! Unless it is a tube radio, I generally do NOT repair car radios. I did come by a crate of Western Electric 350Bs and 300Bs when I was offered some old motor gen set and mobile phones from a car buff. Why yes, I will take WECo tubes as payment.
