Just bought a pair from you guys. Can't believe how closely they are matched! I've bought several things from your store throughout the years and have always been satisfied. Thank you!

I've been using these EH EL34's in my '81 Marshall 2204 for over a decade. These tubes sound great & a real bargain, too! And AES did a great job as always filling & shipping my order quickly.

I bought a set of these tubes for my Germino 68 Plexi replica. What I liked about them was tightness, good detail, slightly suppressed low end, and the high notes had a really nice texture kinda gritty and still clear (don't know of any better descriptive words. What I didn't like was the low notes sounded a little sterile or almost robotic in an electronic way especially with chunking palm mutes while riffing if that makes sense. I liked them but I stuck the JJE34Ls back in bc they sound amazing with that amp.

When I got them they each sat at 31mA, no fluctuations. That is after I had accidentally set the bias way too hot. I had them making some clinking sounds for about 5-10 seconds. I thought for sure I had fried them and they were done for. I fixed the bias issue, and they were right back at 31mA each. Two weeks later they have settled at 31mA and 30mA. That is better than any pair of matched tubes I have ever bought.

They sound fantastic, and break up nicely without going muddy. They definitely held their own even though I sent some tube killing current through them, and still sounding great today.

Will certainly buy again.

Equipment: Scott 272 integrated stereo

Problem: Has a quad of original SED installed, has been performing well for 10 years. Filament on one tube started going recently (shake the tube a little and it will start working again for a bit). Figured that since bias and balance are adjustable, why not buy ONE EH and see if I can get away with it.

The verdict: PERFECT. Slapped the one tube in, let amp warm up a few minutes, had to re-bias and balance ever so slightly. No way to tell sonically there is an "impostor" tube in there. Let it warm up 3-4 hours, conduct all tests again. Nothing moved!

The future: Winged C now too expensive. Will evaluate this arrangement. If the current EH holds up, I will buy three more and replace the remaining SED tubes as they fail with those.

A little puzzled with the reviewer saying it is better to buy the Mullard reissue: blow up the pictures and you will see it is the same structure as the EH.

Excellent tube, to anyone searching for english tone.

Shortest lifespan, probably the worst tone and worst performing EL34 I have used lately. I have a large stash of UK made Mullards, Philips, Telefunken, Tesla (not JJ) and Matsushitas in my shop, and these are total a joke compared to those. Spend a few more dollars and get the Tung Sol re-issue, or Mullard re-issue, or save a few bucks and buy Chinese valves. Or you can buy JJs and have their weird unique tone, but the JJs should last longer too.

Installed the quad set of EL-34 tubes, very close match, bias set and does not drift, tubes balanced and sound quite lovely indeed.
