Hi all,
I'm a new member here, but certainly not new to the Poly 800 (I own two) or modding (I've done the Moogslayer mod on one of my machines).
I'm glad I found this particular thread. Before I became a member today, I found a 2003 thread regarding this mod by doing a Google search. It said to use the NEGATIVE lead of C103.
So last night, I excitedly got to work on the mod, wired it up exactly as instructed and got ... well, a big bunch of nothing. No sound at all. So, I had to replace C103 with a new 10uF cap (since I'd already cut the negative lead loose from the board), and the synth now works again.
Tonight, I'll try 'er again with the revised instructions. I may just replace C103 with a 10uF axial-lead capacitor (soldering in just the negative lead, of course) to make the job a bit easier. I'm eager to hear how this mod sounds!
Cheers to Dave for sharing the revised info (in 2007).
Aaron
