Qty of 10 547DX pentode tube nos submini like 6418
You get a Quantity of 10 - 547DX tubes. They are unused and unmarked from a bulk pack, well wrapped but no tube boxes. They are very tiny tubes for use in battery radios, hearing aids and similar. 1.25vdc filament and 45 plate voltage. Great for tube experimenters. Very similar to the 6418 that is currently being used by AT for AT3060 tube mics except it can handle slightly higher plate voltages. Online tube sellers usually sell these for $10.00 each.
Good tube for making one tube regen radios.
* Typical Transconductace at 30v: 425 umhos
* Plate Resistance at 30v: 750K

If you want a similar tube that has more output and higher voltage then check out my 6088 tube.
If you want a similar tube with a much higher output and higher voltage look for my 5672 tube.
