    PJS replied to the thread Caesar chorus problem.
    I think that Stickman is correct. both those locations would usually be biased to about 4 - 4.5v but both would get that bias voltage...

    PJS replied to the thread Caesar chorus problem.
    Looking at your voltages pins 7 and 8 of IC3 do not look right. I am not sure what they are supposed to be exactly, but they will need...

    So do as I suggested above and temporarily change it to be using the internal programs. That will test to make sure the EEPROM is...

    PJS replied to the thread Pythagoras L78L33 Temperature.
    You are correct - there should b no connection between those points. Somewhere you have introduced a short. Most likely poor...

    Are you using an EEPROM or internal sounds? If you are using an EEPROM try temporarily setting it to the internal sounds and see if...

    PJS replied to the thread 3260.
    From the datasheet it looks as if anything with the Z is the same chip just in a lead (Pb) free package. The A has slightly different...

    PJS replied to the thread Pythagoras L78L33 Temperature.
    More likely something dowstream is pulling too much current - check for shorts.
  • P
    If you try and pull too much current from a regulator it will lose regulation (and get hot). An easy was to pull too much current is a...

    You could solder the jumpers in place, but I would leave the holes for the DIP switches untouched. I would solder jumpers to the solder...

    PJS replied to the thread Muzzle switched socket.
    I don't think so (having not built one). The build docks say that if you are leaving out the key input entirely then you can connect...

    PJS replied to the thread An anemic Seamonk.
    I once spent a long time troubleshooting a build when I finally worked out that I had plugged the guitar into the output and the amp...

    PJS replied to the thread Muzzle switched socket.
    I think that it is a little bit more complicated than the above. The documentation calls for the use of tip and switched tip (and...
  • P
    Nope. You should be getting voltage on the resistor side and gnd on the switch side. If your switch is giving you 8.8v then it is...

    PJS replied to the thread SOLVED Abyss distortion issue.
    That is why I test each resistor with my multimeter before inserting it.

    The 2n7000 FETs in the OCD have protection diodes - it is these diodes that actually do the clipping - nothing to do with the actual FET
