Figured I had best start off here with something worthwhile.
The preamp board is Bancikas design from diyfever.
As he did I used russian 6n2p valves becauses they're so damn cheap and i've heard good things about them for years. 8 for £4... I can't argue with that.
I've added a graphic EQ using a pcb i designed using gyrators to as closely mimic the original GEQ frequency & bandwidth wise.
Things left to add. A transformer isolated DI output so that I can record the raw DI at the same time as the amp signal. I've drawn up and populated the board for this and have used it in the past with good results I just haven't gotten around to adding it yet.
Reverb and a passive insert loop post masters for using it 4cm with my gsp1101 and the most obvious from the photo & built in switchable overdrive.
I will add more photos when I next have it open to work on it.
Also note the chipped top corner. Some idiot managed to drop it down the stairs....
