could an op07 be used in place of lm308?

.25 & .22...i think the board maybe bad, never got a bad board from bean, but i have from a couple other places. I'm going to order a new one & start over!

So, I was thinking, maybe I should replace the d1 for giggles. Also perhaps do a continuity test ...maybe there's a bad trace ?

i put a jumper in & got the same reading

i verified it, red red black gold brown, and i put a new one in for good measure....could it be the zener ?

having trouble with this build, built several over the yrs? My voltage at r7 goes from 9v to .40 ...22r 1/4w resistor... am I losing my mind? am I missing something? after that part seems pretty consistent .40 volts in the build?

Thanks! Yes my transistor tester is cheap! Never had it misidentify before,

#1 bought some j201 on ebay, transistor tester shows "gds" pinout, is this an issue on fatpants build?
#2 bought j201 smd & convertor boards from tayda, transistor tester shows "bjt" is this an issue on fatpants build?

I've only had trouble with the HEADTRIP, and I'm sure it's either builder oriented or possibly a bad fv-1, Bean's stuff is the best.

i get continuity, yes I put a ton of flux on there to make sure it was making good contact, I'm going to clean it and use a little solder paste & hot air just to be sure. how would you socket an smd?

ok, board pics! All other voltages are correct, knobs & switches set as per build document. Pin 10 is consistant at .30 instead of 1.16, continuity tests ok.

C9 is 1.31, no sound out at all, powers up, led works, no bypass or effect signal. Audio probe gives me signal up to jacks idk
