I have recently acquired from eBay a Clarion AC-60 "Jr." (Transformer Corp. of America). Someone obviously has done work on it in the past, since when I removed the chassis some of the wiring and components don't seem to match the schematic that I have. The main problems that I have are 1)only one station, at the extreme high end of the dial, about 1500 Kc., is received. It comes in clearly, but nothing is heard all across the rest of the dial. 2) The station sounds rather "tinny". Any thoughts on where to start? Thanks!

Hi Jeff

Your radio is TRF. Check continuity of your RF coils. Be sure none have been replaced. All 3 stages need to track together.

Jeff, if you can figure out what's wrong, I have a spare chassis that I could send you parts from. It is basically complete except for tuner. You might double check your tuner structure. On mine the tuner pot metal "grew" and distorted out of shape and was absolutly unrepairable. Good Luck.

Thanks David. I'll let you know!

Hi Jeff, As you tune down the dial the tuning gang clases. Make sure the plates aren't touching as it closes. The plates could be bent or the frame distorted. What do you mean by "tinny" sound. Is it distorted or lacking bass? Don Black.

The ganged tuning capacitor seems to work smoothly without any plates touching each other. The "tinny" sound, I guess, means that it seems to be lacking bass. The pitch does drop when the tone control is used, but it does seem to lack the rich bass tones.

Hi Jeff

If your radio uses audio interstage transformers a secondary may be open. Even with secondary open you may have sound but poor low frequency response.

Check audio coupling caps.

Speakers in early radios didn't have a wide frequency response.
