[sdiy] strange analog problem solved

[Nils Pipenbrinck]

Thanks everyone again,

the problem is solved... And I learned some things:

1. Cigarette ash and other dirt can conduct! The right channel magically got
back to life when I cleaned the pcb with a brush.

2. I don't buy a Behringer mixer again.

It was a good deal back when I bought it 'cause I was a student. Behringers
are cheap, but next time I buy a more reliable one. I especially hated that
I have to unsolder the voltage regulators before I can take the pcb out of
the case.

Speaking about the regulators: I hate it when they use LM317 with insulated
plastic package, 7915 without insulation and 7815 with insulation onto one
piece of metal. I had to replace the 317 'cause I broke a leg off, and all
the spare parts I found in my junkbox had a non insulated package. (faked it
with plastic screws and tesa film).

3. I know where I lost my guitar picks. Found three inside sticking between
various parts.
