I made up a bunch of 120 VDC regulated open frame power supply boards
for some of my tube audio projects (go to
http://members.aol.com/ecc81/ps.html for more info). These are
perfect for 6DJ8, 12A_7 tubes run at reduced plate voltage, and
subminiature tubes like 5977, 6021, 6111, 6112, 6814, and so on. The
boards supply a minimum of 28 mA before dropping out of regulation, are
short circuit protected, and use a flat pack, split bobbin transformer
so they can fit into a single rack space enclosure.
I have a surplus of them sitting around. I made extras to sell, but
never got around to promoting them. I'd kinda like to get my cash back
out of these, so I'm dropping my price on these to $29 each until I
liquidate my surplus (or until the end of August, whichever comes
first).
I also have a SMALL surplus of my 12.6 VDC regulated supplies taking up
space. Buy one of each, and the price for both will be $55. The 12.6
VDC boards are the same footprint, and are good to at least 380 mA.
You can power a pair of 12A_7 heaters, or run two pairs of subminiature
heaters in series, (or a single 6DJ8 heater with a power resistor in
series to drop the extra voltage), and still have a little juice left
over to power a few LED's or a solid state circuit.
