Source for Tube Preamp Transformers???

[stevenrotterdam]

Use a small 6 V transformer, and a reverse 6 or 9 V tr to up the voltage again

I 'support' them as much as I support Sinclair gas station when I am on my skiing trip

My opinion might be different if I could still sky, but my back is shot. 😉

Don't want to know who owns them. Probably some stupid equity fund or something.

Your opinion maybe different if you traveled that road, basically desert and you'd take any gas station you could find. 😛
Last time I checked Warren Buffet owned Mouser, at least he has been good about keeping the name, contrary to semiconductor companies that change them more often than I change my socks.

Digikey is a privately owned Minnesota company. Berkshire Hathaway owns Mouser by way of TTI.

I looked at these and the 261 i might be able to make fit. but i would have to add a couple of resistors to drop the voltage down a little bit. or the 262B6 but then i would have to add diodes and caps for a voltage doubler. both MIGHT work.

Maybe this one fits:

Hammond 262B6 has twice the capacity you need, B+ will be a bit high with a doubler, but filter can drop it - dubler-RCRC and you won't need a choke. I doubt you'll find anything smaller. $28 at Mouser - more than I'd like to pay, but I have several similar parts in the basement.

$40.24 CAD for us.

I've just purchased this https://edcorusa.com/en-gb/products/xpwr083a for my 2025 preamp project. Yes it has an 8V winding for DC heater purposes but is physically small.

Lots of people build single-12AX7 stompboxes for guitar. Nixie power supplies are popular for this (DC-DC boost converter). You can buy ready-made PCBs, or build one yourself with a 555 timer and a few parts.
