Everything else is working OK but I was using the Mix Out (LFO out) to
drive my Plan B model 13 when it suddenly stopped outputing its CV signal!

Any thoughts on what could have gone wrong or how to fix it would be
greatly appreciated!

My first idea: the internal connection is broken. It's a blank wire that
connects the solder point "JP4" of all four boards, located behind the mix
polarizer potentiometer at the pcb edge. But I'd wonder why this should
break if the module is connected to Peter Grenader's model 13 :-)

If this is not the reason: check the common output socket.

Otherwise the module has to be repaired.

i had a similar problem with my 143-2.  the normalizing gates didn't 
normalize to env # 1.  the blank wire that went through all four 
circuit boards appeared ok, but further scrutiny revealed that it had 
some "wiggle" to it.  it needed to be soldered again, though the wire 
itself was not broken at all, just too loose to have a good 
connection at the joints. 

as soon as i re-melted the solder that was already there it worked 
perfectly.

Thanks for the advice:)

I check things out tomorrow at work.
