What’s on *YOUR* workbench?

So I've been going hard with my Xtool F1, not least because I wanted to have a couple pedals in working order for this noise gig I'm opening this Saturday, 6/27(Seattle folks, if that's your thing, 8 PM @ Monkey Pub in the U District!) and boy howdy am I stoked. Amir of Amir's Noise Devices remains among the most generous folks in the game as he put me on to not only really consistent laser settings, but also the technique of using paint and an isopropyl alcohol wipe to color the engravings.

I built a Carcass and a Mold Spore. I knew for sure the Carcass would be a great fit for my noise stuff, by gadDAMN I had no idea just how terrific the Mold Spore would be as well. The Chameleons graphic lift on the latter came out too small and after an initial misprint, but it looks messy in a kinda artsy way? Whatever, I just got a jig set in the mail so here's to better alignment going forward!

The implication was that the 6.3V and 345V combination makes a pretty good setup for a tube power supply, but if you really want to overclock your personal massager, there's no law against that either.

How much current it’s able to supply? I’ve been scratching my head and just waiting for a right moment with an amp build on hold for a year. Need to use 240-12VAC trafo for heater filaments as main PT available used series DC heaters previously and there’s no way it can supply enough current for heaters. 4x6L6GCs and 3x12ax7. Suppose power tube filaments should be series connected pairs in parallel and pre tubes paralled through pins 4&5?

6.3V rail is good for 3A and 345V rail is good for like 30mA, this one is intended just for preamps. I have a supply that can do 5A of 6.3V and 140mA of 350V, but the components are physically bigger than I would want to fit in a pedal. They are still smaller than a comparable power transformer would be though, so that's neat. I use those in my tube tester where I need to be able to power things like a 6550.

EDIT: one thing to consider if you're looking at an SMPS for tube heaters though is inrush current, you should typically expect the tube to try to pull at least 200% of its specified current when the tube is heating up, so for 4x 6L6GC and 3x 12AX7 I would target at least 9A for a shared 6.3V heater rail if you're using an SMPS.

I’m using traditional EI trafos. Don’t have any clue about 12VAC trafos current rating, but it’s heavy and salvaged from 80-90s PA/club light unit with metal/gas bulbs. Just gotta be careful and monitor temps under load when finally getting it in use!
