  • also before i go replacing these IC’s am i going to damage them by putting them in this thing if something else is out of whack? I dont really want to buy stuff if the problem is further up the line and im just going to fry them by putting them in.

    Quote:
    14.5v on pins 8, 10 is not good so the clock is suspect – it should be around 7-7.5v with the same voltage on pins 3 & 14. I would replace both the LM311 and the 4013 before spending out on the BBD. Good luck – EH should know that!!!

    Could that simply be because the trim pots are all out of whack?? or does that have nothing to do with the trim pots?

    anyone? as far as I can tell, the trim pots need to be realigned and the SAD1024 chip replaced and the pedal should work again. I have read that there are a few people who can do this. Anyone know roughly how much this would cost if i supplied the SAD1024 chip? I have the chance to buy a V4 reissue for 100$ so I’m trying to weigh whether it would be better to just buy that or get mine fixed. Does the V4 sound much different than the one I have?

    ok so i found an SAD1024 for sale but its going to cost me about 50$ so given all the information above what is the likely hood that this will fix my unit? Should I buy it, or are there any other expense parts which could be the problem that I am aware of? after the SAD1024 chip it’s just fairly cheap capacitors, diodes, resistors and a few cheap IC’s right?

    Yep, mentioned that in the first post

    ” I have even checked the SAD0124 and I am getting 13.9v on pins 5,7,9,11. 14.5v on pins 8, 10. 3.75v on pins 2 15, 4.16v on pin 12 and 4.49 on pin 6.”

    sound goes in on pins 2 and 15, and no sound coming out on 12 and 6 even tho it shows there is some sort of voltage there.

    also getting 14.5 – 14.9 volts at random places throughout the board. basically anywhere after the first transistor.

    Thanks for your help and quick replies by the way. I soooo want this thing to work again.

    i get my guitar signal on pin 2, 15. nothing on 6 and 12. so im assuming the SAD1024 is shot? if so is it possible to replace? also if the SAD1024 was fried, wouldnt i get no signal through the flanged output at all? or does the flanged effect mix with a dry signal or something?

    which pins would those be?
