I'll try and get some photos up.
I have desoldered a few components a few times the reversed BC557 and the J201 and a few wires.y wiring is a bit hackneyed as I use a larger gauge wire than the anchor holes allow but it's never really caused me grief and I've built 6 of these panels in the last 3 years and i'm onto 7th.
The full SSG I built in Dmitri panel #2 works no problem.
I had a similar situation as this on my first panel with a CGS29 Wave Mult. Ended up swapping it out for a Serge Wave Mult.
I'll try the trimmer again too.
Thanks , I'll keep you all posted.

As Neil said pictures would definitely help. Looking at the data sheets the BC557 should be reversed as the pinouts are the other way about to the PN4250.
The issue with the 100n is strange but they are close on the board and also to the BC557 - did you initially have the BC557 the other way round and have to desolder it? Is it possible there's been some damage to the board in that area?
Also have you tried adjusting the trimmer? I built a DUSG this week and was getting nowhere with it until I tried that - sometimes it's not a setting to taste, you need it in the right place for it to work at all.
