Trying to keep the car as original as possible, I finally tested and wired in the original AM radio in my 61 Impala. It works fine although there are a limited number of AM stations available in my area. Problem is, for what ever reason, a previous owner has removed all of the RF filter capacitors and associated brackets on the generator, coil and voltage regulator. I haven’t checked to see if the static collector is still installed. Search as I may, I can’t find the capacitors anywhere on-line. Does anyone have a source for these other than a local salvage yards?
Thanks,
Don

Don,

I'm not aware of a source for new ones unfortunately. Junk yards or ebay are your best bets. Look in your AIM (you DO have one don't you?) and under the radio option, it will give you the correct part numbers. Of course you could buy an NOS radio in the box and it will come with everything.

Is the capacitance value critical? I was wondering if ignition capacitors would work satisfactorily.

Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

I have found that all GM cars used them, and the numbers varied as well as the impedance. AM radio is noise prone, even in my 2016 car. Just find what you can from any GM car starting from about 1955 through when they stopped using points, probably in the 1990's. The ones on eBay are extremely expensive, and not worth the money. There is one on the generator, distributor, and the regulator. Also make sure that you have all the grounding straps in place. The collectors in the wheel dust caps are to deal with static from the bearings and tires.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.
