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.
Tung-Sol has reissued the rare 7189, a high fidelity audio specific variation on the EL84 tube. In addition to the increased fidelity, the 7189 features a higher maximum plate voltage rating of 400V. These tubes are great for both guitar and HiFi amplifiers and can be used in any EL84 or 6BQ5 position.
Starting at $46.60
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
