Frying an OC44?

I have a rangemaster (negative ground, oc44) in the testing/prototyping stage, and i replaced the 68k resistor with a 100k trimpot to mess with the bias. While messing around with the bias, i was playing guitar, hit a chord, and it just decayed.

Now i get a faint sound out of the pedal. I replaced the trim with the regular 68k resistor, and same deal...

did i fry the oc44?

What voltages are you measuring on the C, B & E ?

HAHA  ;D

noob mistake, i yanked out the powersupply by accident  :D


just for reference anyway.
What are good voltages for the C B and E (negative ground, oc44) that i could shoot for when biasing?
