I'm updating the SRA-3S i bought recently. It was pretty cheap ($65) in as-is condition untested, so they said. I've never powered it up. I read through the thread in the diy subforum and saw Spritzer's recommendations. Looking at my driver board, I think I don't have enough capacitors? There are four small ceramics that just have a "5" on them which i presume to be 5pf, and appear to be in the positions in the schematic that specify 10pf. I'm getting some mica caps to replace those. But where are the four 0.05uf caps that he recommends to upgrade to 0.22uf? There are two ceramic blobs on the back marked "5-D" that i don't really understand, unless there were supposed to be two more of them? I suppose i should desolder one and measure it. The trimpots were removed for replacement. EDIT: Nevermind, I'm a dumbass, they're on the main board.

Slightly less explicit here.
