Best Source for Replacement/Upgrade Tubes??


Who have you used for replacement and/or upgrade tubes for both pre and power amps?

Thanks

I've had great results buying tubes from Jon at The Tube Store. He knows his tubes and the service is excellent.

Every tube I've purchased off eBay has been bad. And one pair of very expensive tubes that I purchased here went bad inside of two weeks. FWIW, I only go with the bigger suppliers now. Among them:
www.partsconnexion.com
www.tubestore.com
www.tubedepot.com
www.conusaudio.com

If you don't have a tube tester, and complete confidence in the seller, be careful. NOS tubes are a delicate lot.
All the best,
Howard
