Coopersonic - Dirtbox and Valveslapper guts

Photos not good enough to trace the circuits, but thought these might be of interest to UKers.

Hi there,

Sorry to bump up this old and dead post, but if any member of this forum can post detailed images of both sides of the valveslapper pcb (in case to have acces to one of this units), I promise to do my best to trace this dirtbox and post the resultant schematic here.

Looks like is enough remove four knobs, unscrew the potentiometer nuts and cut a couple of cable ties, to have freedom to take detailed shots of the track and components sides of the mentioned pcb.

The psu looks like the usual 555 based nixie power supply found googling schematics in the web, so the tube board is the only mystery to solve.

Thanks in advance,
Jose
