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 - 7189A, Pentode, Beam
New-Old-Stock (NOS) tube. The 7189A is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers. It differs from the 7189 in having a higher screen-voltage rating and in specifying the internal connections to pins 1 and 6. See T-7189

Vacuum Tube - 7189, Pentode, Beam
New-Old-Stock (NOS) tube. The 7189 is a power-amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and high-fidelity amplifiers. It differs from the 7189A in having a lower screen-voltage rating and no internal connections to pins 1 and 6. It cannot be used as a replacement for a 7591A in most situations.
