I bought a raggedy General Washington off eBay the other day, everything that glitters ain’t gold, remember this.
It came in the mail, looks like it’s almost new, was pleased. Powered it up, no magical puffs of smoke, pleases again. Hooked it up to my service monitor and tested the output, again, much pleased.
Problem with me being pleased came when I tested the receiver, completely dead. Turning the monitor up to a signal as strong as S9+30 dbm, absolutely nothing. A hum and steady ticking or popping is all that can be heard.
Talkback is fine, the PA is fine, transmitted audio is fine but there is absolutely nothing on receive. No meter movement at all. I figured maybe the protection diodes had an issue, changed them, nothing. Thought maybe TR17 was bad, nothing upon changing it out. My other thread about a tester is in relation to this radio and this problem.
I’ve tried swapping out and testing also, TR16, the squelch amp/control, nodda. I have checked or changed every disc cap from the beginning of the tap, I believe it’s C43, all the way to about L8 I believe. They all show good.
I’m burned out. I’ve walked away from it twice and moved on to other repairs and projects but when I go back to this devil radio, I’m still fresh out of ideas. I feel like maybe I’m overlooking something simple, so I’m asking for ideas or input here, my brain is frazzled at the moment. I’ll give a better account of what parts I’ve tested or replaced in my next posting. Thanks!
