A rare piece of non functional equipment, a Nadine’s Distortion on the workbench.
Gut shot, the circuit board in nice condition.
The 6552 opamp was burnt, once replaced the pedal’s rocking again. Image of the circuit board with a socketed RC4558 as replacement for the 6552, the old electrolytic capacitors changed and a new battery clip installed.
The circuit board of the Bull pedal. There’s silicone diodes clipping and in the front of the image you ses two germanium AA144 diodes. There’s three BC184 transistors and one 2N3904. Posted earlier here.
Just had to take this picture. A cap from the 1950:s vs a modern one, same uF and voltage rating.
Here’s a gut shot from the new prototype of the Maestro PS-1A clone.
