There was a post either in this thread or on the other forum, suggesting that I might need some more filtering. Well I clipped in another 220uf cap parallel with C43B. There was no change to the B+ supply but the picture seemed a bit more stable. Hmm..... so I added another 220uf to C43A and again the B+ stayed the same abd the picture remained stable.
So if I add these E-caps to each C43A and C43B it will bring each up to 440uf. Does anybody see anything wrong with doing that? Would a lesser uf work?
I'm including a picture of that section of the schematic.
