Boss DD-3 repaired

Checked the switch for D.TIME due to the problem of changing from 200mS to 800mS of delay. Found it’s not the cause. Had the wiring from the switch resoldered and it’s hey, it’s back in normal operation! Also fixed the knob for E.LEVEL wich was glued in place.

Mullard GE diodes

Found these vintage OA5 germanium diodes in the box of vintage stuff. Beutiful diodes indeed. Got to make something with them, just don’t know what? Anyone care for a custom built pedal with these beuties under the hood and in what circuit?

I like how the circuit board appears in black and white.
