Default Re: More Chinese AM radio kits

I decided to isolate the audio output transistors and transformers from the circuit board to try and find the fault. For this purpose, I used a homebrew mono amplifier that runs on a 9V battery. My guess was right and the radio works and tunes fine as it should using my external amp. I might use the board to make a larger superhet or maybe transplant it into a non-working desktop radio. It should be easy enough to make wired connections for a larger tuning cap and volume control pot.
