I had to replace the Power Supply on my 2000s and 1000s and I tought I would post the parts list and schematic for it all. This mod has been tested for six months giging and in the studio and is working well. The Transformer is made by One Electron model BFT-1B, the solid state rectifiers are HEXFREDS Rated 16A@1200V, Capacitors are Solen Fast Caps. I have a separate transformer for the Bias supply.I put new tubes all the way around and rebiased. It is sounding great. If you want to look at the power supply schematic I have posted it as an Acrobat doc at this link.
