Where do you guys buy replacement tubes?


I'm sure it's been covered, but I haven't found it. I'm looking to replace my sons tubes in his amp. We have had some bad experiences to date with suppliers and I would like your recommendations on good suppliers. His amp uses 6336A tubes, a real odd ball, so the supplier needs to cover alot of types I would guess. Thanks for your help, J.D.

What a fantastic set of posts. I just want to thank everyone who took the time here to try and help me. I have tried all the sites and have found I must really call these folks to get a proper information. I would incourage all to visit some of these sites. There is a great deal of history and theory on a few of the sites that became a wonderful education for me. Thank-you again to all, and please feel free to use this post to further list suppliers, or to discuss results of certain suppliers. Thank-you Kevin for your input, I think you taking the time to post shows how much you do care. I hope other suppliers will take the time to promote them selves or to help solve problems. J.D.
Kevin is a straight up guy and did allow a return of unused tubes when an amp aquisition fell through for me. I will continue to do business with him as I believe you can't put a price on having confidence in what you are purchasing.His recommendations are excellent as well.
I hope I don't give the wrong impression. If you call a typical tube store, the owner, let alone anyone else, will not talk to you about what will sound best. Ther are a couple botique dealers that will, but they don't have the stock we do as it is a side job typically.

I have not wanted to give up helping every customer myself....but I think it's silly to think someone else here can't do it. But the challenge is...none of the fine folks that work here know the sonic changes that occured in, say, an Audio Researh SP-9 MKI, vs a MKII and MKIII. I happened to live through that stuff.

We will become a smidge more "automated" via on-line ordering for the experienced tube-head. That should help. I just don't want people to think we are too busy for personal attention. That's what it's all about. But it's customers first. They deserve that. If a guy buys an amp on Audiogon and can't figure out how to use it, he should call the seller or manufacturer. I would never ask another dealer to take care of my customers questions.

I would like to add that the order that I placed with ATSI went smoothly and that the tubes were well packed and promptly shipped (they sound good too). I also made an Ebay purchase from a dealer (user name Roytang) that is new to Ebay and as of today has 15 positive feedbacks. Roy is located in Hong Kong and accepts PayPal. The tubes were excellent NOS Sylvania Gold 5687's (and sound really good as well), they arrived almost as quickly as my domestic (continental USA) purchases. Also thank you Kevin, for taking time to comment (I once had a job with the phone company where I took up to 115 phone calls a day and know where you are coming from).
Hello again:

I would like to add another source that I used recently for Svetlana 300B tubes which is (http://conusaudio.com). The tubes are specially selected stock (not branded for export) that the dealer received directly from Svetlana and they come with an 180 day warranty. For those of you that are concerned with the past reliablity issue of Svetlana tubes (as I was) there is a brief summary at the website of what went wrong during the production period in which "those" tubes were manufactured and it is a must read, IMO. I now have over 100 hours on the Svetlana's and they are excellent in my setup, smooth and "natural" sounding, yet detailed (very musical). Conus carries other tubes as well and Euguene, the owner, has been a pleasure to deal with.
