Source for LDR? For rebuilding trem circuits

[1ampman]

Greeting, I've had several amps with bad opto-coupler. Not sure what to buy to replace the light dependant resistor & where to get them. Rebuilding seems like the only option if it's not Fender. I appreciate any help....

Assuming you are in the US try Jameco. I've bought these with great success you have to bend the leads of the LDR and hold it all together with heatshrink.

I've used the same LDRs that Nick posted with no problems at all. I bought 100 for £1 a few years ago. All the mainstream electronic suppliers were getting rid of non-ROHS stock in a panic and there were some insane bargains. They never thought it through that a cadmium cell would still be listed as non-ROHS anyhow after the smoke cleared.

I bought a grab bag of those photocells from Jameco a long time ago, and still have a couple. Worked fine.

I just ordered 10 of each.
