Vintage Synth Repair

Hi,
  I posted this at the odysseypatch group also. Can someone that has
an Odyssey please provide some info:

  I installed one of the new sliders from synthfool and it feels
great! I replaced the osc. 2 PW Mod slider. I can't recall (such an
idiot) its previous behavior though. When I have the switch under the
Mod slider set to ADSR the sound goes away when you raise the slider
all the way up. Is this normal? Osc 1 doesn't do this. Also, the LFO
switch setting seems to operate normally. FYI-I did adjust the 50% PW
trimmer to thin it out some at the max. slider setting but this
pertains to the other (50%-Min) slider under osc. 2 PW.

This is a Mk-I 2800 whiteface. I hope I've provided enough info here.

regards,
