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.

Solid State Replacements

Solid state replacements for vacuum tubes are great for use for hard to find or costly vacuum tubes and for reducing 'sag' in power supply applications.
