I too recently bought a used 2900. I also bought the service manual including schematic diagrams. I think my mods will be limited to replacing the low-to-medium-quality electrolytic output-coupling caps with bypassed Black Gates.
There've been lots of comments on the modded 2900s here; I'll be interested in comments posted.
