Title: Looking for full schematics of Randall RH100/RH200 and Peavey XXL
Post by: Raul341 on June 12, 2025, 04:14:43 AM
Hi everyone,

I'm currently working on a personal solid-state amp project, and I'm drawing inspiration from some of the classic transistor amps I've always admired. In particular, I'm looking for the complete schematics of the following models:

Randall RH200 G2 / RH100 , etc

Peavey XXL Transtube

I already have the power amp sections, but what I really need now are the full schematics, especially the preamplifier sections, which are key to capturing the character and tone I'm aiming for in my build.

If anyone has access to these schematics or can point me in the right direction, I'd really appreciate it. I'm also open to sharing schematics or technical info in exchange if that helps.

Thanks a lot in advance! :dbtu:
Raul

You may have to contact Peavey for the preamp schematic.
What is available online is what you probably already have. (the power board)
