Tube Buddy B9A

$--.--
  • A heads up on power!

    If you're tinkering with tubes you've got to be careful. Not only can you ZAP yourself something fierce, but if left unchecked, an excessive current drawn can cause the board to burn up on you. Based on the trace width and thickness of the Tube Buddy B9A, be careful not to exceed about 4 amps of current and 300V.

About The Tube Buddy B9A

Playing with tubes means working with high voltages. So bench-top ergonomics becomes a critical consideration, not just for tidiness but to help avoid clumsy, painful shocks.

The TUBE BUDDY B9A is sold as an unassembled, DIY kit that will neatly break out the pins of any B9A tube for you to then wire up on a breadboard or other project setting. Convenient test points make reading voltages a one-handed job - quick and easy!
