Ok Guys. I have a Washingotn, 858PLL. @ off them actually, my old one is now a parts radio for this one. When I got it it only did like 8 watts PEP, My old one did 21 with the 1307 final, But I drove it low at 12. ( I kow what they are rated for). Anyway, this one had all sorts of noise toys and the unlocked clarifier, and channels. needless to say it was a hacked mess. After getting the frequency expansion right, new mic jack, new driver (2166), final(efl20W), regulators, power suppy caps, recieve mods, alignment on tx/rx. It will do 11 watts PEP, no more. I am told the audio is a bit muffled.
I tried different mics, removed the compressor circuit, changed the predriver FET, broadbanded it, un broadbanded it, lol.
Started changing caps one by one.
I tried a different relay I mean I am at a loss as to why it is only putting out half power.
It has 13.8 Vdc steady under TX with the rebuilt powersupply board.
The driver and final get 13.8 under TX on SSB, bias seems right.
I dunno, suggestions? Some where to start probing?
73's and thanks
