EAT Tubes

EAT reputably manufacture some of the world’s best 300B, KT88, ECC803 & EC88 audio tubes.

The tubes are precision manufactured in a factory (a portion of the old Tesla tube factory) in Prague, Czech Republic which cranks out the parts and materials, and then final assembly and listening sessions with reference source materials take place in Switzerland. As a result of the very high focus on fine tolerances, EAT can claim a life expectancy that is about 50% longer than normal valves.

EAT KT88 diamond, gold pin audio valve


The EAT KT88 tube is in a league of its own. This KT88 tube is available in factory-matched pairs & quartets. Its construction features include black plates, black metal base, and gold pins.

The EAT KT88 has an designed maximum anode dissipation rating of 35W and is recommended for use in the output stage of an a.f. amplifier. Two valves in class AB1 give a continuous output of up to 100W. The KT88 is also suitable for use as a series valve in stabilized power supply.

EAT 300B Valves


These tubes appear to be designed from the ground up. They are better at dynamics and sonic neutrality than vintage (or reissue vintage) tubes while remaining ultra smooth and state-of-the-art detailed. This is 21st Century tube sound for the world’s best phono and SACD reproduction. You cannot go wrong running EAT 300Bs in any application.

EAT ECC88 Cool Valve Diamond reference audio valve fitted with Cool Damper


Many people prefer the sound of EAT ECC88 triodes tubes for their "soft" saturation characteristics which can be quite pleasing to the ear!

The ECC88 Double Triode valve comes with a Cool Damper pre fitted which offers a more controlled and deeper bass, a more open and detailed sound stage, and crisper and greater dynamic range.

Equivlent tubes: E88C / 6DL4 / 6T

EAT ECC803 Cool Valve Diamond reference audio valve fitted with Cool Damper


The ECC803 Double Triode valve comes with a Cool Damper pre fitted which offers a more controlled and deeper bass, a more open and detailed sound stage, and crisper and greater dynamic range.

All EAT Cool Valve ECC803S's are required to pass through rigorous testing to meet EAT's high standards. As a result of this selective process, all ECC803S's are matched to very similar specifications.

Equivlent tubes: 12AX7 / 5751 / 7025 / 12AD7 / 12DT7 / 7729 / 6681 / 7058

I had a Steampunk project and needed a couple dozen valves for props. Paul was extremely friendly and helped me build up a collection of neat looking ones that will certainly add to the theme. Overall a great person and very passionate about sourcing and seeing these valves go to good use (even though it's not for an amp or radio!).

Paul has helped enormously re-valve my collection of vintage valve amps. Using his test equipment, he painstakingly tested over 100 valves, grading and categorising them and was able to supply either directly or through his extensive network all those requiring replacement due to either non function or matching equivalents. I can now be reassured the valves I'm using are of the best quality and fit for purpose. I would recommend Paul assess your valve requirements and rate his knowledge highly

flyboy39 (124 124 positive feedback) Thu 17 Apr 2014

Paul sent me 11 high quality valves to test in my fender twin reverb. He said he doesn't like to push people into certain valves which is great because i know my taste can be very different from others. I was impressed by the variety and quality of the valves and even more impressed by the sound when i rolled the vales through the amp. In the end i settled on 2 nice 12AX7 and 1 nice 12AT7. my amp sounds amazing now! only problem is.... i think i want to try every valve now!?!?

What great service Paul sent me 4 sets of tubes to try with no obligation to buy. One of the sets of tubes he sent me absolutely transformed my system, a system which incidentally cost wise is approaching $80K. From my perspective and dealings over seas I believe Pauls prices and service are up there with the best and I really did appreciated being given the opportunity to try before buy so am I wrapped in his products and service you betcha. Barry New Plymouth Thanks Paul

Paul's Service is outstanding. He sent 4 valves to me in Dunedin to try in my preamp, with no obligation to buy. I found one that gave me the results I was looking for, and Paul was very careful not to influence my choice. Its hard to imagine a better way to buy valves!

Paul is an extraordinary guy to deal with. He has helped me improve my system with the right selection of valves, he is always assertive and knowledgeable and this of course has improved my listening experience; my music will never be the same thanks to Paul. As he recommends, rolling the valves of your gear will lead to a new way of enjoying music. Cheers!

all I can say about Paul is wow! he is a top bloke that totally knows his stuff regarding all NOS valves in the world and he has it all. Cant say I have met someone like him before, he puts TRUST in people by sending them valves to try to get a feel on what these valves can do and I am very impressed! He help me find the right valve tube (Amperex 6DJ8 / Bugle Boy) for my Aune T1 DAC and it has made my DAC a top notch device. Thanks again Paul, will find you again for 12AX7's soon!

I am very impressed with the service that Paul provided. He found an electric eye valve for my old Pye radio. He sent them down for me to try, on trust, he has old fashioned values. If anyone is looking for old valves go to Paul first.

to all those traders out there, remember the days when trademe first started when you could trust most traders (kiwi's) to be honest, but not so much these days unfortuately, but this guy is still one of those guys you can trust 100%,sent me down 8 mullards nos valves, to tube roll,with no payment made to him &rolled them in my amp as he desribed them they were a beauitful sound,he's got just about every tube you can think of,or will find it for you,if he can,even from Russia,amazingly helpful.

Paul is a great person to deal with. A Futura radio being restored needed a 6A7 valve, but was very difficult to find. Luckily I came across Paul's advertisement on Trademe and inquired. To my delight, he had new (unused) valve still in the original carton. He sent it securely to me by post, and the radio is happily singing now! Thanks Paul. Highly appreciate your service to the vintage radio enthusiasts. Sarath

Paul has been a great help in finding the right values for my ears/system i have now had 5 pairs and what different a good valve makes Thanks Paul
luckyr (85 ) Thu 22 Nov

Paul supplied me with a quad of beautiful Vintage Mullard xf2's to try in my Yaqin amp. They are the most amazing tube I have used so far, it's safe to say they are staying put in the amp. Thanks Paul.

Thankyou Paul great service with exceptional communication throughout the process . I will recommend with confidence to any one searching for tubes to enhance and breath new life into the old school amplifiers as well as up grades as was the case with my spark amp , all the best regards Clive Riley.

I am a harmonica player and the problem with using guitar amps for harp is that guitars need hi gain valves in the pre amp section...not good for harp as it means you get feedback at very low volume settings on the amp, Pete sent me a selection of quality vintage low gain valves which I tried and swapped around till my amps gain was at the desired level, I can now drive my amp at a good working feedback free level. Pete's excellent service allowed me to get a harp friendly amp real easily..!!
