Hey there folks,
   I was foiled again by a bad DC jack - not a good batch from Tayda this time around apparently. This is the second of the lot that has been junk. Unfortunately, I fear I may have zapped something in my troubleshooting ventures. She's getting signal through, but it's very weak. Does anyone have some key voltages available for this board? Spent the overnight working so I'm heading to bed, but the first order of business is getting an audio probe and a test enclosure going tomorrow (today.) While I sleep, however, I thought the friendly elves of the forum might fill my troubleshooting stocking with their gifts of wisdom.

Thanks again, Brian. Your boards are great and this site has been a simply amazing tool for learning my way through all this. Can't say enough ...

I've built 4 pedals this week, so I was due for a problem. I will admit, I've done very limited troubleshooting because it's 3 in the moring and at this point I'm too stupid. Upon attempting to bias my mangler (built with NOS trannies from Small Bear) I was greeted with a negative voltage reading of .6. What gives?
