Hi Doug,<br>
<br>
Why not use transformers for step up/down use? Obviously the xfmr
would be pretty useless at LFO frequencies, but at 20Hz up, an
audio-quality part should work fine. Take the 150V tube sigs down to 15v,
and the 0-15v up to 150.. Has the added benefit of excellent DC isolation
for the circuits, and introduces the prospect of using the differential
output of the transformer to drive a balanced line to the next module, or
to the mixer/recorder... excellent for keeping s/n high at this point in
the sound creation process..<br>
<br>
<blockquote type=cite cite> BTW, I do not believe that there is any
great <br>
danger of fatal shock with these circuits, the output <br>
currents are quite small.<br>

Thanks for that bit of sanity... unless one has a heart condition, the
currents are pretty minute. <br>
