More Vacuum Tubes recently added at bottom of page

Special Item Myers Tubular Audion Vacuum Tube

Rare early Myers tubular audion, tested for filament continuity and tests good. Will include a xerox copy of the instruction sheet.  The end caps wiggle a little but do not rotate. $49

Pair of vintage Sylvania 2A3 Tubes

Pair of vintage Sylvania 2A3 tubes that test as new at 72 and 74 so very closely matched. Auditioned and they sound great. $165 for the pair

Couple of 2A3 Tubes Haltron and National

Haltron 2A3 Printed with Made in England, tests as new at 78 auditioned and sounds great $65

Vintage Hapsco dual flat plate 2A3 tube Made in USA

Rare and highly sought after Vintage dual flat plate plate 2A3 tube, tests as new at 70 on TV-7D/U tube tester, branded Hapsco, Made in USA. Auditioned and sounds great. $79

Valvart 2A3 Tube (noisy)

This is a new old stock Chinese Valvart 2A3 tube that tests as new at 74, but when auditioned has some static you can hear when there is no sound input. You can't hear it when there is music playing, and in fact the music sounds great, but should be considered defective with the baseline static noise. Should still be safe to use and will sell cheap at $9.

Regulated 0-50 Volt DC 1.5 Amp military spec power supply

Regulated DC Power supply 0-50 Volts at 1.5 Amps, military unit in working condition. I have used it for B+ power for tube radios and works fine for that. With the voltage dials turned all the way down it still measures about 2.7 volts, so may not be useful for voltages lower than that in its current condition. Heavy duty military construction but also fairly heavy so check with me about the shipping cost if  you are interested. $21HOLD   (a tiny fraction of the original cost to the military)
