Blackstar HT100 Barbecue: Replacing The Tube Board.
Either way it had a major cookout which lunched the tube board. Lucky for me it is a separate piece of hardware AND there was available a schematic for the tube board.
Looking at the diagram it seemed that I could hand wire it ala Marshall and then I'd figure out how to connect it to the main board. So I installed four ceramic sockets and started in on the wiring and resistors and hookup wire.
When I got to connecting the tube board to the main board, removing the molex connectors was going to be problematic because they're glued to the board. I decided to make loops in the ends of the hookup wires, and lucky me, there was enough separation so that I wasn't going to have problems with bridging.
I finished the wiring today and it powered up the first time. So tonight I'll let it have a slow simmer and see how it goes.
