Zu Omen is a good choice but depends on how loud you want to listen and where you place your speakers. In this nearfield setup, I've used Axis LS28, VoiceBox S and Whaferdale Diamond 10.1. My Elekit TU-8200 drives them all very well.

Thanks, all relevant info I failed to provide sorry

This won't be for nearfield, rather for a living room with a chair near by for headfi duties. Speakers will need to be close to the wall so sealed or front ported at my options.

@bcowen please stop me from buying this Elekit.... because I already have so many frigging tube amps !!! But this one is screaming, 'Buy Me' !!!

This would have been perfect and would have been mine but I am waiting for Odyssey and he's taking his sweet time coming home.

I’m still very happy with my Elekit 8200. I run E80CC’s as well as NOS ECC82’s (Mullard/Philips/Valvo and Brimar). Power tubes that I have used are amongst others Osram KT66 Grey, early 1950’s Mullard EL37, Mullard EL34 (XF2, XF3 and XF4), RCA 6L6GC BP, GE 6L6GC, Sylvania 6L6GC. I like the fact that through tube rolling you can adjust the sound to fit with your headphones. The mid emphasis of the Mullard EL34’s for instance accommodate the Beyer T1.1 very well.

I have a substantial collection of Philips 4699 metalrim tubes that I would like try out as well. Has anyone tried these in their Elekit yet?

Nobody using the Philips 4699 with EL34 adapters?

My TU-8200 still under repair. Otherwise I will be tube rolling

That sounds quite serious. I hope not due to tube rolling. Have you ever tried the 4699 met rim in the Elekit? It’s supposed to be even better than Mullard EL34.

I was using a NOS NIB pair of Sylvania 807 when the left tube go up in flames and took out the TU-8200. A guy I know is repairing it now but getting parts in this Covid times requires patience. I've not use 4699 but I have used Philips Miniwatt 6CA7 xf2 double O getters and RFT EL34. A seller I know has Philips Miniwatt 6CA7 double D getters brown base and also the metal base for me but I have put on hold anymore tubes buying until I get my custom KT88 / EL34 set amp. That is coming soon from Sweden.

Hi allI bought 2 pairs of 807s with adapters from a reputable seller. With both pairs, after a couple of minutes, sound goes out in one channel and the LED turns orange. Turn off the Elekit, change tubes and all is well. That happened a couple of times. Oddly with 5933 tubes it works quite well! Any guess?

When that happens it’s a warning and I think you shouldn’t continue to use those 807.

Even though other earlier owners reported that it’s ok to use 807 in Elekit TU-8200, I’m not a 100% convinced, especially with what happens to my amp and these warnings signs on yours.

Thx for the heads up. I was about to buy a couple of ceramic VTS-25 but will rethink this now.

Yeah I haven't tried to use them more. On the other hand, the 5933 sound and work just fine! What is really happening to those 807s and the amp? How does that protection works with the LED turning orange?

 

[Ovide]

I think that the fet’s blow when the light turns orange. I have several fet’s in reserve, just in case. But I think it is good practice to first test your tubes before trying them out in the Elekit.

 

[Effusion]

I've used dozens of 807s in the 8200 over the years, including ceramic ATS-25s, without issue. I have also blown two FETs thus far, knock on wood! On the DX version, the light always turned purple I believe when the FETs blew (it's been awhile). Both times the tubes were bad, with one blowing while running in the amp! The newer R version has protections built-in, so this may be where the orange light and sound stopping, without blowing a FET comes in. @aedaza, do you happen to have the 8200R?

Initially I was unaware of the 807 type working in the 8200, but I found a few meet/show pictures of Victor's early on where he was running them and he told me they were okay to use in the amp. I've enjoyed them quite a bit since, especially the ATS-25s, but often find them lacking the finesse of certain other NOS types, however those at much higher prices. They do however usually sound much better than many others I have, often having a nice in-between sound.

One issue I ran into is that US 807s tend to have a bigger top pin than their European counterparts. I actually have 3 sets of adapters now; some fit the US snugly, but are loose on the Europeans (I only use them if they are snug), and others that fit the Europeans snugly, but won't even begin to fit over the tip of the top pin on the US ones. I'd have to count, but I think I have around 70 or so 807s at this point, all sorts of manufactures/variants, smoked, ceramic, hand-painted, etc.

I'm no expert, but Victor should be able to address any concerns regarding the 807s and/or technical questions of their use in the amp, R and pre-R, through Mr. Fujita.

I hope this helps! Keep on rocking those 8200s!
