Thanks Wavrider and Nomad, I checked the resistors and did find R711 out of spec. 1/2 watt 330ohm had changed to 6 ohm. I replaced it but didn't get any change yet. I do have the complete service manual and schematic. I would have never gotten this far without it. I admit, I struggle with the schematics sometimes.
I did have to change out c706 on this one due to it being jackhammered and broken. Luckily I had a replacement from a donor. I used the By Gosh By Gum method and the neutralization went fine. No oscillation on SSB, transmit was on frequency. I'm thinking were good. BUT, I did not set the bias then. For some reason I got mixed up and was thinking I don't have to do that, this one is fixed bias..... (Yes, I'm a dummy)
Now, back to where we are...bias on AM RX was -24.5, adjusted to -40. SSB RX bias was -46 and will not set any lower, the trimmer is on the stop. I try to peak t700 for max -dc volts on channel 20 TX and nothing, no change at all. Because they interact with one another, I see if c706 will make a difference and it does not. T700 and C706 makes no change no matter where they are set. Readings were taken in crystal mode.
Thanks
