I can contribute with these pics... sadly I couldn't read the value of the cap marked with "unknown value"... and I didn't want to desolder it... by the way, that was one of the green film caps in my unit... not a ceramic.

I hope you find these useful!

Does anyone have any idea about how to calibrate the various trimmers on this circuit?

I have one of these that I've been trying to work some random, static-y, noises out of. I'm not so hot reading schematics, and I'm wondering if anyone could help me identify the little guy I circled in the attached image. Hope it's ok I borrowed the image above; in my pedal the resistor is kind of cooked and the color bands are hard to make out.

It looks like a 220Ω 1/2 watt to me.
The same value as the resistor in the lower left corner of the image that you posted.
Look at your phaser to verify that value.

Hey folks!

Sorry to ressurect a zombie thread...

Bit does anyone have any idea as how to calibrate the 5 trimmers inside this thing?

I've somehwat ressurected a dead unit (new bulb, retaping the shutter) but the trimmers have been monkeyed with to the point where this thing sounds nothing like it should.

Any ideas???

Thanks!
