CODE 50 faulty power supply

All Questions

Hi,

Marshall user since early time, I work also in electronics repairs.

A customer brought me a faulty code 50 power amp. Is there any way to get a new power supply from spare parts to replace it ? I thought replace the original PS with a standard one but the original one gives 2 power supplies: main power an bluetooth power.
In the worst case where we cannot find spare parts, it is possible to get schematics or at least the values of the voltages ?

It will be cool to bring back to life this amazing stuff from a ledgendary brand

Thanks in advance

Hi Sensatioa 2016 model and it looks like it could be a common fault . The power from mains was terminating at choke 1 on the power supply board.She I desoldered this it fell in half .It appears that the cage material is very brittle and is liable to crack when the pins are pinched to hold the device on the board.This leads to a crack and eventually the 2 wires break loose from the pins . resulting directly n a dead amp. Desolder ,clean the enamel off the ends of the wire and tin . Superglue the plastic frame back together and resolder the tinned wires to the pins . This is a 1:1 choke so it doesn't matter which way it goes back!in. Resolder the pins to the PCB ensuring not too much heat to undo the soldering repair and the amp should come alive again !
