Problem with a Rat.

[supernaut]

Update: I've taken it to a mate of mine that used to repair electronics for a living. He's showed me proper soldering etc And built a silicon fuzz face clone while I watched so I could get an idea of how not to make mistakes.

I've decided I am just rebuilding the board. The one I had has been desoldered. I will be using new veroboard (and mostly new components).

Once that's done and working (hopefully) I'll provide another update here with some video/sound clips. Probably be up on Sunday if there aren't any issues.

I do want to say thanks for the help, this has been really educational for me.

Sorry to resurrect a very old thread, but was there ever an answer as to why pin 6 was pulling up to the positive rail?  I am having the same issue on my proco rat build and I can't figure out how to fix it.  Some bridge somewhere?  Thanks

Bridge is the most common issue..

A less frequent cause could be "open" NFB loop (no connection between pins 6 & 3)..
Op-amp is saturated to positive supply rail due to extremely high open loop gain..
