Vacuum Tubes

The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
T-EL509-S-JJ Vacuum Tube - EL509, JJ Electronics
The JJ Electronic EL509S is an eight pin octal based version of the EL509 / EL519. This modified version does not have the top plate cap which is instead wired to a pin on the octal base. This tube is rated for 700V and 42 Watts plate dissipation. The JJ EL509 is popularly used in output transformerless OTL amplifiers.
