Serge panel external wiring

2004-09-08 by Hamachi

Hi gang! This is my first post to the list, but I've been reading it for a
while. I first fell in love with the Serge back around 1981, and
eventually bought one (6 panels) about 10 or 15 years ago.

Well, I lent it to someone for a few years, and he cut it into 3 pairs of
panels, trying to isolate a known short (what he hadn't known was that I
had already removed the bad module from the circuit). Somewhere along the
way, a pair of panels was lost, and he returned 2 pairs and a big pile of
banana cords. Sigh. Oh well. I got over it; better to have 4 panels than
none.

At any rate, I need to patch these back together, and give 'em
power. Looking at the bundles going between the panels, I see upwards of 3
complete sets of black/white/red/green wires. I am aware of the voltage
color-coding. My question is actually pretty simple: is there any reason
why I couldn't solder all the greens together, all the reds together,
etc? I mean, they're all going to the same lead eventually on the power
supply, why do they need to be separate?

Thanks

Believe it or not - it makes a difference, especially with the grounds.
Daisy chaining them to one PSU connection can lead to noise problems which
love to pop their pointy little heads up in reverb springs (don't know if
yours is so equipped) - but they will effect other parts of the audio path
as well and anything that remotely involves counters or shift registers
(programmer, TBK, sequencer, asr's) Remember, the Serge doesn't use shielded
patch cabling. In the system I had here for repair, the click of the
electronic ignition on my stove was enough to bleed into the audio path -
and it wasn't as if the Serge was in my kitchen! If I were you, at very
least I would do direct connections per panel on the grounds to the PSU.

On my system (not a Serge) I do direct connections to every half panel, and
in some instances (those pesky lowpass gates and sequencers) its on a
by-module basis.

Life is too short for hummmmmmmmmmmmmmm.

regarding losing panels: sound like you're over the shock and have long
since forgiven, but friends like this you don't need!
