Hi. My Eastern Electric Minimax BBA has suddenly developed a dead channel. Swapped out valves, but its dead as a doornail. Does anyone have a clue what it could be or what i should test?

Failing that do you know of a good repair service in Europe (Germany, Netherlands)? Shipping it to and from UK Post brexit will cost me big money.

Thanks
Adrian

Hi Adrian, do you have a schematic for your amp? After swapping valves did the heaters light up? I don't know the EEM stuff but you could possibly start testing from the power transformer onwards. If the filaments are not getting power then look at that first. Once the valves glow as normal and still no sound then trace the signal from the inputs.
