    It's also possible that it's a component in both of the amps getting ready to fail, and if so, I wish that it would just hurry up and get it over with.

    That's more a rack power strip with pull out convenience lights and basic AC filtering and something like a Metal Oxide Varistor for Surge protecting. It's good for RF and EMI interference.... but it isn't doing anything for a variable Voltage stability and true clean power

    I mean it might be possible that you've worn out both amps with overdriving the pre (I'm guessing your not killing the power/post these days in your backyard.) and you got a pre amp component in both that has the same warm up/temperature issue because you've smacked both amps in the face with way way way high level from your MT2 or something like that.

    I also checked the power supply feeding my pedals. The junction where the wire meets the transformer was frayed and I could see copper. Replaced it with a new power supply. Ran the Randall through it's paces (with an X2N and a Metalzone) and it seemed to hold up just fine.
    Warmed up the Picovalve and gave it a check and it seemed good too.
    Hopefully it holds up. I think that the power supply was the primary issue and the fluctuation that I thought that I heard playing direct was due to the loop levels being maxed in the Randall. I'll put it down to ear fatigue playing direct into the Picovalve (no separate gain channel on that one).
    So, as it's been said, so far, so good (and yes, so what).
    Thanks to all for the assistance.
