Default Mezmerize DCB1 without Salas Shunt Reg

The pcb is almost complete, you will need a pot, a selector switch and a +/-9V PSU.
The matched quad 2sk170bl-s are from Spencer.
Relays: EA2-12NJ NEC | Mouser
Resistors: Dale RN55D / RN60D
The Mezmerize was tested with the Salas shunt reg.
The traces are not cutted just scratched.
The price : 25 EUR + shipping.
PayPal preferred.

He, he, like a sawed off shotgun. Not complete but still deadly.

Recommend +/-10V as best though.

Ooops!

I forgot it, that's the PSU for the 7812 which drives the relays.
So, it needs an additional ~+18V.
I will post photo soon.

Thanks!

Even +15V will be enough and it can be tapped off the main filter capacitor of the positive rail.
