I'm no expert, but it looks to me like you put 68pf cap across lugs 2 and 3, not 1 and 2. Also, to jumper the resistor at R49, I think you will remove the resistor and put a metal wire in it's place.Well, it took me weeks but I finally have time to try and fix this amp. Here are some pictures; if there are no obvious errors I'll re-solder all of the modded caps.
Here's a link with pictures that show you what I'm talking about.

I'm about to attempt these mods myself. Hope I do it right.
