Welcome to tctubes.com!
 
We are a small midwestern business founded by a husband and wife team (Tyler and Chelsea). After collecting vacuum tubes and tube related gear for more than a decade as a way of supporting our hi-fi audio hobby, we have decided to take it to the next level.
 
Tyler’s audio interests began more than 20 years ago where most cool guys in the ’80s started—solid state stereo systems built to pump thousands of watts into booming subwoofers. But unlike most cool guys, he was interested in building systems that actually sounded better, not just bigger. That’s the interest that led him from solid state to tube audio. The latest amplifier he built was a whopping 0.75 watt of sweet tube sound.
 
This website combines Tyler’s tube audio expertise with Chelsea’s e-commerce experience. Starting this small business is our response to the challenges of this economy. We hope to gain enough momentum to be able to hire some folks in our neighborhood who are looking for work. We also hope you’ll enjoy the service and the prices we are able to offer with our low-overhead business model.

Customer Comments

I received the tubes in the mail, intact and in good working order. Thanks for the great sounding tubes and for your careful packaging and handling of them for their long journey.
-- Rosemary, Ontario, 4/9/15

Received your beautifully packed shipment of matched 6V6 tubes last week. Put them in my tweed Fender Deluxe today. Perfect in every way. After dealing with with less than professional tube folks, you guys are my heroes. I'll be stocking up on 6V6's. I appreciate your care in shipping and attention to detail.
-- Mike, Louisianna, 3/30/15

Very happy with my purchase of the Lafayette LA-310 power amplifier. Looks and sounds wonderful; a museum-quality unit that's also a reliable daily driver!
-- Steve, Missouri, 3/26/15

I just wanted to thank you guys for all the great tubes I purchased recently. Between the matched sets of input and power tubes, the system sounds Great! My wife says it sounds like we made a 10k upgrade.
-- Douglas, Virginia, 3/22/15

The replacement Siemens triple mica 1966 12AT7 was unexpected. I am sure more than 60 days had elapsed since I made the purchase of a pair and one failed. I sent it back not expecting to get a replacement but to my surprise and delight you did just that. No questions asked. I am a delighted client and will return for more.
-- Rick Brown, Hi Fi One, California, 2/9/15

I just wanted to say thank you for great service and fast shipping of my tubes. I can rely on folks like you to get the real deal as opposed to taking a risk on e-bay.
-- Tim, Illinois, 2/4/15

Hello TC, got my tubes. Thank you very much! Nice packaging. It shows that you care for the customer as the way they are shipped. I have had some that were bad, and you wonder if they are going to work. You all take care.
-- Duane, Illinois, 1/28/15

Got my shipment on Saturday, installed them on Sunday and have been grinning ever since…..I will keep and share your site info with my fellow musicians that appreciate tube amps.
-- Reyn, Georgia, 12/16/14

Just a note to thank you for the EH 6ca7 quad! These are terrific sounding tubes! They all biased within 2ma of each other and are very stable.
-- Stephen, Nebraska, 12/2/14

I got the Gold Lion tubes yesterday, played music for 4 hours with stereo image dead center...I am now a very happy customer and delighted audiophile! Thank you very much Tyler and Chelsea for the nicely matched Gold Lion tubes.
-- Bruno, Canada, 10/22/14

I received the tube in good condition, it is playing at this very moment, thank you very much.

Everything arrived safely and in perfect condition. Thank you again for your support.
-- Carlos, Spain, 9/2/14

I received the tubes today. I like how you have clearly marked on the tube boxes all details. I wish all sellers did that. Excellent work. I hope to do business with you again.
-- Peter, Australia, 8/6/14

Hello, thanks, the tubes arrived very good.
-- Andrés, Chile, 8/5/14

Just wanted to say how pleased I am with the IEC Mullard ax7 I recently purchased. It was my first Mullard and wow does it ever live up to the legendary hype! I am spoiled forever! Thanks!
-- Paul, New York, 8/3/14

Hi, I just read your page: "Interpreting Amplitrex AT1000 tube tester results", and wanted to thank you for such an excellent informative piece! Superb and so helpful.
-- Keith, UK, 7/24/14

Hi Chelsea, tubes arrived, all ok. very good , many thanks and cheers from Italy in particular from Modena, city of motors (Ferrari, Maserati, Zonda and very near to Lamborghini).
-- Augusto, Itlay, 7/17/14

Your comparison of various results for the EL34 with the Amplitrex and 3 other classic testers, is the best example I've seen about weak emissions not showing up on a transconductance tester. I've been testing a few thousand tubes with two TV7, a 752A, and a Sencore Mighty Mite IV. I have to use the Sencore just to make sure the tubes will actually work. Otherwise, I'll send out "matched" tubes that aren't even close for a real amp. The Sencore does a good job of showing dead cathodes. My 752a has the cathode bias resistor option on it, so I wired in a meter. It's been amazing to see the wide ranges of cathode emissions when testing tubes on that one, and it doesn't always correlate to transconductance.
-- Philip, USA

Just want to say the tube did arrive today and is already playing.... Impressive!
-- Harald, The Netherlands, 7/3/14

I ordered a quad of Sylvania 6SN7GTB black plates from you earlier this month. I installed them in my Mystere ia21 integrated stereo amp, replacing the OEM tubes. It didn't take long for them to sweeten up the sound. While the highs are about the same, the lows really strengthened - and tightened up a bit as well. After running them about 20 hours now, they've noticeably improved the sound all-around. My system has never sounded better!
-- Mike, Wisconsin, 6/16/14

People half a world apart have to have a lot of trust when doing business, or somebody will get messed around. Thanks that I can and do trust you guys, and for the quality tubes you send me.
-- Wayne, Thailand, 5/28/14

Just wanted to let you know that I have received the tubes, installed them - and they sound awesome!! Thanks you so much for designating their locations! Been a real pleasure working with you and I sure appreciate your services!
-- Peter, Virginia, 3/7/14

I wanted to comment on the recent shipment I received from you folks. I rarely correspond concerning good service because I expect it. It's only when something goes wrong do I feel the need to contact a vendor. The shipment I received yesterday though caught me a little off guard. It was obvious from the moment I opened it that someone had taken great care to package it. The time spent doing it right and carefully was impressive. I order from other tube vendors and they do a respectable job, but this was more than I expected.
-- James, North Carolina, 1/14/14

Just received my Tung-Sol 56 triode tubes and couldn't be happier with the quality of the tubes and the terrific service.
-- Mark, Washington, 1/5/14

I have just recieved the tubes safe and sound at home with no probem at all. I 've tried them already and after they warm up they start sounding like liquid cristal, clear, full and sweet. I'm amazed of how well you do your work so definitely I'm 100% like this :) and like this :o = wow.  I know it is too early but merry christmas and keep on rocking. Cheers.
