What is the "thing" thats between the radio and the speakers? Heard it was called a AMP, BOOSTER, AND something to cool the radio,which I know sounds dumb!Do I need it, and what does it do? Thanks so much!Larry!

Re: C3/Radio

The device that you described is a "connvector". Basically, it is a germanium transistor mounted in a finned, aluminum heat sink. Normally, this would be part of the radio chassis assembly for automotive transistor-type radios of the 60s. However, due to the "packaging" requirements of the 68-76 Corvette radio, it was seperated from the radio and located under the right side dash panel. You ABSOLUTELY need it; without it the radio will not function.In Appreciation of John Hinckley -

Thanks joe, that was a big help!Comment

Agree with Joe, to a point....
The convector was used on all non-stereo radios. If you had the FM stereo optional radio, then this 'block' component grew more complex and provided both FM stereo de-mux as well as final LH/RH speaker drive functions and these 'critters' are harder to come by...Comment

Yes, for stereo radios GM referred to the "external device" as an "adapter". However, the stereo radio "adapter" was mounted more centrally in the dash and not under the right side dash pad, per se. Consequently, and since Larry mentioned the fact that the device was under the right side dash pad, I inferred that he was refering to a non-stereo (U-69) radio.In Appreciation of John HinckleyComment

Correction
Larry didn't say that the device was under the right side dash panel; my mistake. However, he did say that the device was "between the radio and the speakers". In that case, he probably does have a stereo radio and the device is called an "adapter" per GM parlance. The "adapter" is wired between the radio unit and the speakers; the non-stereo "convector" actually is wired directly to the radio unit only.In Appreciation of John HinckleyComment

Re: Correction
My 74 has the adapter and is mounted between the speakers as you mention, somewhere above the radio. FWIW, back in 78 or so, I temporarily replaced my GM radio with an aftermarket whatever brand with cassette tape, and it was the sorriest swap I ever did.....alternator whine, ignition spark static, I tried every filter asm I could get my hands on....with little improvement. It was such a joke I took it out within 2 months and put the good ol GM radio and adapter back in...no more noise in the radio!! GM knew how to design a radio for the plastic car!!!....CraigComment
