Ok, sorry for the off color topic, but the problem is kinda funny!
I built a dual loop "dumbleator", with relay switching and a footswitch, it's a really nice piece. Having free space in the rack box and noting some similarities between the "return loop" and a standard stage, I put the vibrato from a vibro-champ in, along with a switch which disables the local feedback on that stage. Lastly, I set it up with a DPDT relay which both grounds the osc. (turning it on) and connects it to the stage, so the pot doesn't load the stage when the vib is off.
When it's set to max int. at low speed, it's perfect. When you start putting some speed on it, the helicopter takes off. I've built a footpedal to go with it as I love the sound of vibrato being dialed down from fast to slow (see: trey anastasio) so I don't want to start tinkering with the overall range of the vib.
speed.
The voltage on the return stage is a little hairy when it's happening, climbing from about 205 to around 300 as the cathode voltage ranges from 1.5 to about 4 or a bit more, which I thought was what was supposed to happen... Under normal conditions the voltages are all spot on.
I apologize in advance as I'm (3600) miles away from my home computer and don't really have schematics for this here. It's a vibrochamp vib hooked to the return stage of a dumbleator. Thank you for any opinions or possible solutions. I'm pretty stuck.
