Marshall Amp Power Valves Relocation

A great sounding amp, but poor design. With the power amp valves mounted horizontally & direct to the PCB, there just was never going to be enough air flow for heat dissipation. After the amp let me down twice, it was time to fix or get rid.

The two octal sockets holding the 5881 power amp valves were cut from the PCB and mounted onto the underside of the chassis facing vertically down.
