HH guitar combo, 2*12" schematic

[pecamuzicar]

This vintage (model IC100L, or 212, or V-S MUSICIAN, or all ?) solid state combo amp is one of the best sounding guitar amps what I ever heard, with rich creamy sound and powerful.

I found some schematic, but is not clear which model, I am not sure. There I saw some specific chip used for simulation of "valve sound": V-S MUSICIAN Tone correction module AS00015/A. That is IC, or just module with separated PCB?

If this is the module with PCB, please if some of you have a schematic?

Also whether is this schematic of amp about I talk? If its not, please I need right complete schematic.

Thanks in forward!
