The Fine Things are Always Hand Made
Ok gang...so I have an AW 23 that I fully restored about 4-5 years ago. Played great. For lots of reasons, it hasn't been run much since then. I ran it up on the Variac this weekend, and here's what happened: AM and first SW band are dead, and the osc VR tubes don't light. On SW2 and SW3, osc VR lights up and the set plays great. Good audio on the phono input too.
So I take the tuner apart and check the osc circuit. The grid resistor is significantly off value, so I replace it. Clean contacts (which were still very clean), and still nothing. Voltage is only slightly below the VR threshold on AM and SW1, but just low enough for the tubes not to fire...and no signal. I'm stumped at this point.
Thoughts and suggestions appreciated!
