My TSL 122 Combo keeps red plating the tubes. Everyone says these amps have the same kind of issues, but Marshall won't do anything about them, except to but a new board (thanks for sticking behind your products!). Anyone have any other suggestions? Thanks much!
Hello Dean,
We would recommend that you have your TSL 122 looked at by an engineer so they check the amplfiier over for you and investigate where the fault lies, as the fault could be in the power supply or the in the power stage.
