Vacuum Tubes!

We have over 4000 tubes in stock, primarily New Old Stock (NOS) tubes in their original boxes or used and tested with excellent results. Please contact us with your specific requirements. Below, you’ll find a list of available tubes. The quantities and brands vary depending on the tube number. We can also match any tubes on our uTracer 6 curve tracer, even using positive grid voltage when necessary, or use any of our calibrated mutual conductance testers. We offer matched pairs/quads and include curve trace data with purchases if requested. Feel free to reach out to us using the Contact Us section.
