Ok so here's the background. I've had my amp and preamp for about a year and a half. I did a few things to it like re-caping the control board and adding a speaker protection circuit. I became aware of the White Oak upgrades by watching amps on ebay. Now we are jumping ahead to current time. I pestered the spouse for the control board rev-E kit and the power supply capacitor kit for xmas. So I get the kits and have the week off and jump in head first. You know that part where you are supposed to thoroughly read all instruction, was out the window. I didn't start asking questions until I couldn't get the bias to set right. Not terrible but definitely on the high side. I think that was probably not so much my fault. Joe sent me an update to fix that. I completely spaced on the part where I was supposed to replace all the output transistors. I ordered those from Joe and they arrived today. I headed to my favorite local electronics store for mica insulators which are the kind that I prefer. I believe the heat sink grease works better and don't care about it being messy. I figure you can't see it with the covers over the transistors anyway. So I get there and they only have 2 for $1.50 each which is both disappointing and over priced. So now I've ordered them from Mouser for $.19 each. In week or so and I'll have the rest of my parts and be back at it. My next PL project will be to re-cap my PL 2000 preamp. Does anybody make a kit for that?
