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.
Vacuum Tube - 2D21 / PL21, Thyratron
Miniature, four-electrode, inert-gas-filled thyratron with negative control characteristics of the tube include a high control ratio essentially independent of temperature over a wide range low grid-anode capacitance and very low grid current.
