Jeffhs, he's talking about 740 KTRH in Houston, not Toronto.

How are you feeding the radio? There's a choke back there in the 12 volt power line. If you're feeding from a power supply with excess ripple, that could cause vibration. Best results would be to run it from your 12V car battery.

I would think that once recapped and aligned per the instructions on page 19 of that schematic, the stations will fall into place. This radio has a 262 Khz IF. A quick check would be to put the signal generator on 262 with modulated output and place the output lead near line 24 of the schematic. Should hear the tone. If not, IF may be off.

Another test: put an operating radio tuned to 1260 next to the Delco and tune the Delco around. If the Delco when tuned around 1000 produces a squeal or rush in the operating radio it means the oscillator is working, but with the stations not agreeing with the dial now, this may not happen.

Don't understand the statement about audio being louder before the output choke...as picked up by what? Signal tracer?
