  • Fender roach - resistance

    What is the rest resistance of the opto-resistor in a fender roach?

    Cheers!

    As far as I know, when the LDR is in complete darkness, the resistance should be about 1 megohm.

      Agree.
      To be honest, I thought you had gotten an amp to repair, long forgotten in some dirty restaurant kitchen or pantry.
      Just yesterday I was reading in a Pro repair Forum guys discussing roach infested amps, one which had over 1 inch of rat poop inside, a Marshall tube head with a dead mother rat inside, complete with her babies, dead slugs shorting contacts inside Hammond organs and some other similar delights.
      Ugh !!
