I picked up one of these cheap at a music store yard sale, and was trying to spruce it up (dusting, pot cleaning, cabinet re-do).  While it would be within my capacity to reverse engineer it (its a TDA2030-based unit), it's a royal PITA to disassemble and reassemble.  Right now, the barrier separating it from functionality would appear to be an above-the-board connection between some soldering terminals that I foolishly kept no notes on.

If you have a schematic, or a gut shot or can simply tell me where thew wires go to on yours, I'd deeply appreciate it.
