So I guess my question is: now that I have a ss rectified circuit (presumably the same as in the 2000s), how do I transplant it into the schematic I have (2000s)?
If you're going to be messing around with an amp of this nature, then you should have enough knowledge to figure this out for yourself. AC wiring can be extremely dangerous (lethal) if not done correctly, and the same with the DC wiring inside the amp. Basically, the solid state diodes go into the 2000S in place of the GZ34 wiring, but you have to have
some knowledge to know what to snip and clip and what to keep. If you haven't yet, read some books on amp design like the Kevin O'Connor series of books, Dave Funk's Tube Amp Workbook, the Gerald Weber books, the Jack Darr book, etc. If you read enough and really study it, you'll gain the knowledge to do this yourself, and you will be able to do it safely too.
For the diodes used, a 1N4007 would be just fine wherever they call for a diode. Back in the day, they didn't specify parts as completely as they do these days. The yellow leads may not be needed so they are just tied and taped off. Often a transformer would be purchased for a design that would have been used for another purpose because the price was good, and they would just use the parts of it that they needed.
If you were building from scratch and wanted to do this the easiest way, build the amp for tube rectification, and then use Weber Copper Caps in place of the tube rectifiers. He makes some that are just like solid state diodes in addition to the ones that emulate tube voltage drop. Then you can use either/or....whichever suits you. Since you already have the amp, and it is setup for solid state, I'd just roll with it as is.
