I continue going through this neglected radio and I think I have got most of the gremlins exorcised except SSB power. Receive seems fine so I left the synthesizer alignments alone and I went through the transmitter alignments and have about 2.5W dead-key and 5-5.5 W modulated. I have set the SSB bias and carrier null but can only get a little less than 2W out on both USB and LSB.
The only adjustments that did not go perfectly is the USB and LSB carrier freq adjust. They are both off and adjusting the associated trimmers doesn't seem to have any effect on the frequency.
Just for grins I replaced ALL of the electrolytics on the audio and main boards, cleaned all trim-pots before adjusting, etc. Any ideas of what else to look at would be appreciated.
