Good tip on the main filts. I looked up what I did on one and I had used Nichicon Gold Tunes with solder lug connections.

The screw terminals on the UCC's definitely look easier to use than those solder lugs in this application. Glad someone found these caps.
I just finished (well almost) the right P700 Power Amp board. Replaced all of the components listed in Leestereo's rebuild thread, plus I did replace the diodes at H718/719 as noted by hirscwi. I didn't know if the ones present were the later upgrade or not. I felt like they were because they had the glass look, but I had the 1N4148's on hand, so replaced them. This was my first time to replace a differential pair (H701/702). I Hfe matched them, put a dab of heatsink compound on the flat faces and closed them together with shrink wrap. I did find one problem that I will have to go back and fix after I get the part. R746, a 22ohm, 3W resistor had been getting very hot. The plastic lead wrap was totally melted along with the wrap on Diodes H720 and H721. I have two questions about this: Will this 22ohm, 5W wirewound resistor work as a good replacement?

And, since I'm going to have to remove diodes H720 and H721 to replace the lead wrap, I'm wondering if I should replace them. They are listed in the SM as 1S2471 (black). I found one place that said a 1N4148 was a substitute for this diode. Does that sound right in anyone's experience? Thanks! Here are a few pics.
