how did I miss this post? anyways, I have to add the gratuitous ZYX

is right... another imod thread? this is your first post here!

the adapters are pretty easy to make. Hardest part in my case was drilling a hole in the base for the top cap, as those bases are pretty fragile when drilling at that angle. You won't have to worry about this. I like to use bases and sockets that fit inside each other, then once the adapter is tested then I can secure the two together with an appropriate adhesive. I've also found that using PCB sockets work better that the loop style, as they are more compact when pushing the socket into the base. Just make sure you use proper temperature (and voltage) rated wire and you'll be fine.

ah, 12.6V is only a single switch away! And so many more (cheaper) tube options await you, not to mention less current draw.

I was thinking more of the former, case-in-point Nelson Pass's rig

Including a Lowther OB?

once you get the 7n7 up on adapters, they will be pretty tall, assuming you make adapters the same way I do.. then again, all my adapters have plate caps on them... don't forget about the 7af7, and perhaps it's time to think about a 12.6v heater option for your psu... this results in............ more tubes!

Which do you prefer these days, the beta22 or the consonance integrated?

sure you don't want a few extra parts to start your BOM? Otherwise they're going to get added back into the void of my part closet.

Thrice: I may have some extra UX4 sockets laying around... Bakelite and gold machined pins, like the ones sold on Ebay. Interested?

grawk: or buy an existing KGSS and just modify it to have 620v

looks amazing Steve!!

I think we are a dying breed.

jp: did you ever get a hold of a modded Museatex DAC? If so, what did you think?

especially the yellow RT. Both Charles Hansen and John Curl say they're the best caps they've heard. I tend to agree.

cool. if you happen to get a dud or random extra tube, I'd be interested in using it to test my psu

bump. So, I got the following for 2 tubes Earl mentioned: 6c33 12.6V => 2.8A-3.6A 6.3V => 5.6A-7.2A 6528 6.3V => 5.0A nate, you got anything to top that for the menace?

where's pabbi1 these days?

press Mikhail on what he means by this, as there is still AC I'd wager... not B+, but AC heaters nonetheless.

I think a 100% DIY rig is minimalist. At least, that's what's looped on the recording that I put under my wife's pillow at night

I'd like to say 2008 is the start of the stat dynasty

I'd still like to see a picture of the critter. I'm finishing up an external heater supply that can supply 2 x 7.5A of DC filament current and has a 6.3 and 12.6v switch, so I can have switch these supplies independently. I'm tentatively calling it "the bench warmer", for obvious reasons. I considered working in an external pass device to go even higher, but I'm not sure if it's needed... so, the question for Earl and Nate: What tubes have you run across with the most demanding heater requirements? I'd appreciate a heads up so I can decide about the pass device someone soon. I'm most interested in tubes that have high current requirements that don't have center tapped heaters, since in this case I'd use the lower current option, since I can.

nope neither do. Probably Esoteric / TEAC you're thinking of.

They come free of charge with the caps ........ (bad joke) anyways, those *are* the caps..

nate, just to point something out... the Plitron transformers that Mikhail uses are potted / encapsulated, so what you see on top of the amp is the toroid itself, not a cover or something.
