That's my old amp, 100%, for sure. Psychopomp is what I named the amp.

That black tube glued to the cap in the front is/should be a blue LED (pictured).
After the third of fourth one Tom stopped making them. They were to expensive and extremely time consuming. The other 2 or 3 in existence of the 60 watt Omni-Tone (he made 15 watters, which the Omni-Tone was original), were completely different than yours. That particular power section was only made for that Cauble.

TheFlyn may know what Tom has been up to, I believe they know each IRL.
I also just realized/remembered your amp description is/was the the same as the e-mail (copy paste?) that Tom sent me.
Also, there's something I'm forgetting, about the power switching... I remember him telling me on the phone, and it not being written down.
That amp sounds amazing, and I've missed it every day. Sold it along with 5 other amps and built my recording studio. Costs ran higher than expected; it was the only thing I could move as fast as needed.
I think I waited 6-8 months for that monster, with one send back for tweaking, or was it two send backs.. I can't remember.
EDIT::
I sold it to branjispad who sold it to JoshuaLogan, then dropthisd bought it; I believe after that it popped up a few years later on TheGearPage, so you might be the 6th or 7th owner.
I also found a picture with another Omni-Tone (which looks similar to yours) with the LED on, I added that picture, and yet another Omni-Tone 60 that had different cosmetics.
