Bypass works but mahayana does not turn on...

[Dirt_diggler]

Unfortunately I ran out of hook up wire so I had to use scraps of pieces I had. Apologies for the mess. I seem to have everything hooked up according to the generic wire diagram on the mahayana pdf. Another thing I was wondering is if It is ok to use a 3 prong dc jack if I do not plan to use a battery snap?

I'm curious if I hooked up the switch wrong.

1. does your LED turn on when you are not in bypass mode?
2. please use your meter and give us the voltage readings for every pin on the IC and on the transistors.

My led does not turn in in bypass or engaged. I will report back with readings tonight.

So I dropped my pedal off with a repair guy last week. He called me today to tell me my wiring was 100% and that I had a bad chip. He gave me a tl072 and installed a new led because mine was not working.

Haven't had a chance to listen to the pedal yet but I'm very excited.

Has anyone here dealt with replacements from mouser? Are they fair?

I mean, do you have other Op Amps you can try ie JRC4558D, TL072

I did suggest that you try other Op Amps, That is why this Forum is here????

You did and I'm not taking that away from you. I even said I was going to pull one from a pedal and try it. However I ran out of time and had a short window to drop this off before I wouldn't be able to mess with it for a few days. He's a friend. It was beer money. Life happens. I'm happy. Thank you all for you help.
