Freshly serviced Marshall Valvestate 8100. Great condition for its age, everything works as it should. Only issue is the tolex coming up in the back of the amp (common with these) which you can see in the pictures.


Electrolytic capacitors replaced July 1st, 2026 (all Nichicon high quality caps)

All pots replaced, all new on July 2nd, 2026 (Alpha pots)

All knobs replaced July 2nd, 2026

New JJ 12AX7 installed mid June 2026

All jacks/switches treated with Deoxit (no bad contacts)

Reverb tank wires resoldered properly

Fixed a few lifted pads from someones prior repair attempt on a few opamps


The amp sounds great, and is super loud into a 4 ohm cab. If you are looking at this ad, I'm sure you already know what it's capable of.
