Replacement circuit for Marshall DSL40c V1 amplifier
« on: May 10, 2024, 03:27:55 pm »
Hi, guys

I have e DSL40C that has a lot of issues and a not good sound.

I would like to ask you guys if is it possible to replace marshall PCB for a one channel el34 base amp board, to work with marshall cabinet, transformers, pots, tubes and etc?

If yes, witch sellers do you recommend me to buy this kit/components?

It's a bad idea?

Cheers!!!

The DSL40 has 2 channels and you would like to replace the whole circuit with a single channel board.

I doubt it's possible.
1- To find a board
2- to fit the board in the amp.

I could be wrong.

Can't the current circuit be repaired? That is the best option

Yes, it's possible. Hoffman sells the board and parts for a Plexi 50. This is not a paint-by-numbers kit, and the linked drawings are the only instructions. Requires electronic knowledge and basic fabrication skills, tool, etc. Are you up to the task?
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Use the chassis and transformers to build something else. It'll be fun! And way more durable than a DSL 👍
