You should get a pair of Brimar 12au7 long plates. Beats the Psvane or Gold Lion 12au7 any day. They aren't too expensive ... yet. These drivers stay in my amp and has not been changed for weeks. I can get Amperex and Tung Sol 1960s 12au7 at $400 a pair but I'm in no hurry because the cheaper Brimar is very good. Remember to get the long plates. They are better than the short ones.

This Sunday. I'm just commuting between Sydney and Canberra. A tale of 2 cities. Despite all the other good sounding amp, I'm still particularly fond of the Elekit combo. Each time I change the NOS power tubes, I get a different tone... different but wonderful.

You have some very nice tubes for the amp so I'm not surprised you miss it.

I'm excited to listen to the amp, but I'm also excited to work on the build. When I built the Crack, it was a happy time to finally get to listen to it when it was completed, but it was also sad to be done with the construction. So maybe I will just go slow and enjoy this one.

It's always fun when you build your own amp. You can say, I made it !!! However don't go too slow because TU-8200R sounds better when completed.

Luckily I have some other amps to keep me entertained in the meantime, but most of them I did not build.

Good idea on the Brimar tubes. They are still affordable.

I wouldn't mind building it over. I was in a hurry to build mine, I missed a solder joint. After I kept hearing a crackle opened up unit and found it. Purist say resistors/ capacitors should not touch the circuit board, I'd like to place them all with a little air gap.

Is it safe to run 5814wa tubes in the tu8200r (and tu8500)?

From what I can see 12AU7 draws in 150/300mA compared to the 5814A that draws in 175/350mA.

Thankyou

Interesting question. Have you tried your premium 6SN7 tubes on the TU-8200 amp, @UntilThen ?

If 6SN7 works, then it should be safe to run 5814 tubes.

No. I don't believe you can use 6SN7 in TU-8200 amp. Someone here change the transformer to be able to do that. I won't go to that extend.

My new SET amp Odyssey though can use 6SL7, 6SN7, 12au7, 12at7, 12ax7 as well as 2 x Telefunken EL11.

Cool, you've got some really nice 6SN7 tubes, it would be great if they work on the TU-8200 amp.

I sold off some of my very nice 6sn7 together with Studio Six amp. Now I have to start collecting them again.

Fortunately my new amp need only one double triode to work. Pretty much like my previous Glenn OTL and Studio Six.

Top of my list to get are ECC32, ECC33, Sylvania 6sn7w metal base, RCA 5692, Tung Sol 6sn7gt bgrp, Sylvania 6sn7gt bad boys 3 holes.

 

[cddc]

I remember you had some really nice ECC32's, kind of pity you sold them off. They are now harder to find and quite expensive to buy.

That's the circle of life. I thought I have given up tubes lol.

Came back to my TU-8200 after one week and I could not believe what I've miss. If this is the only amp I'll ever get, then I'd be totally happy.

What is your current set of tubes in the amp? Brimar 12AU7 and what power tubes?

Would you have any thoughts on how the psvane 12au7 differ to the brimars?
