moving "whine" noise from buffer

[pufferton]

here is my situation. I built a stereo buffer for the end of my PT Pro rig. its powered from a BBE Supacharger which is Edison'd off a Voodoo Lab 2.

i play live in 2 hour blocks. the last two times i have played (first was 45 mins in, second was 1hr in) the pedal started to make a high pitch whine. not like white noise but a tonal frequency.

The weird thing is when i started to play after it "whined" the tone would "move" down to my guitar note and seems to slightly digitally bit-crush it. when i stopped playing it would rise up to its "resting place" like at 12k hz.

The only way to stop it was to unplug the the power line to the pedal briefly and plug it back in. the whine would go away and the pedal would be fine for the rest of my playing. obviously live this isn't ideal.

i have 11 other pedals on my board split between the two bricks with no other issues.

could it be a bad component? power brick? ground wiring? radio signals? help?!

First thing I'd try would be a different power supply.  If it tracks that then maybe you can just live with that separate power supply.  I don't think anything that would cause such a whine is actually IN the buffer.  Supposedly the BBE power supply is isolated per output so I wouldn't suspect a ground loop if that's true.

Are you staying within the current specs of the SupaCharger for all other devices?

I got questions about a PP2 setup where it was going funny after some time on. The problem was that the regulators in the PP2 were overheating, and running out of bulk DC from the trannie. This particular PP2 wasn't able to power all the regulators at full power all the time, and still get out the heat or avoid running into loss of regulation.

I don't know if it's a generic problem with them or this unit had something wrong with it internally. Lowering the loading on it fixed the problem.

the buffer isnt powered from the PP2 but the Supacharger that is plugged into the outlet on the PP2.

Im powering all my low mA pedals off the Supa while powering all my higher ones off the PP2 (dl4, Timefactor, rv5, etc) the only thing i know im doing wrong is powering the Eventide off one Iso out instead of coupling it. i haven't had any issues with my Timefactor by doing this (8-12 months at avg 12 hours/week)

the only time i heard the noise is adding this buffer i built to the Supa. i have had more plugged into the Supacharger before (5 months back) but removed some of the pedals.

thats what makes me think its the buffer since when i quickly disconnect/reconnect the power to the buffer the whine stops.

i can try a different power supply for the next few days to see if that helps. again as mentioned above im 99% confident im well within the mA per output but ill try and double check that tonight too.

i ran the buffer on a separate power supply and had no issues. im gonna try running it off the PP2 to see if that also works. so far the Supa is the culprit.

and ran it off of the PP2 and again no issues....so if i run the buffer off the Supa it gives the noise....what gives? i know the Supa's arent the best but they aren't crap either...

so for one gig my board was plugged in for 6 hours. 4 hours into that i came back to it and noticed the "whine" noise. the buffer was plugged into my PP2. as soon as i unplugged/plugged it back in the problem resolved and was good for the last two hours...so far it looks like after an hour the buffer whines with the Supa and after 4 hours the buffer whines with the PP2...is this an issue with my buffer that i could resolve?
