Request Marshall MG100HCFX schematic

[Rajan Paliwale]

Yesterday I got it( Marshall MG100 HCFX) for repairs.The foot switch connecting circuit is burnt.Kindly help me find the schematic for it.Thank you all.

This is the new disposable series,I don't think it's possible to repair if smd parts are burnt,no scheme.

Very simple circuitry.
Repaired for 5 min.

Why part schematic, why not the whole schematics.

I would assume because of NDA (non-disclosure agreement).

Do you have the power transistor section of the schematic?

I think that Marshall series MG100... in output uses IC TDA7293.
Maybe can help schematis for Marshall MG100HDFX

nope,the cfx one has discrete transistors in CFP configuration,the fan spins only when it gets too hot,i repaired one reflowing some solderings,lead free is the best you know....
