Just finished my transformer board. Ghetto circuit board work here (only had big wires, so wiring everything up under there would have been hell). But hey, no shorts, so I've got nothing to complain about!
The heatsinks are mounted to the PCB by 2 metal pins right?
If you really don't want to buy new heatsinks, you can forcefully pull the heatsink off the pins then desolder the pins and put them back in.
I've done this before and succeeded.
but try not to damage the PCB in the process (because want it )
The transformer looks awfully small for such a big amp... looks like 12VA to me...
