I just picked up a used Torii mkII, sounds great  looks great , but does have alittle hum in it, did all the thing listed on this site about hum and I think it the 5u4 tubes. The hum is in both channels, you can hear it in the hornshoppe horns about a foot away. What tubes are you guys using in you amps, thanks Greg

Jim, I want to thank you again for your help. I did order today a set of JJ GZ34 /5AR4 to try out an see if that will lowe the noise floor alittle more, most of the music I play is loud Jazz and fusion and Blues, with some Rock, I can`t here it when I sit down and you can`t hear it with the music I `m playing, but the room is dead quite and it does get under my sin alittle when I get near the speakers to change albums or CD. I do like the sound of this amp alot and I believe I can get it to sing soon , thanks again . Greg

Just an update on the tubes, I did get some JJ GZ34/5AR4, this did lower the noise in the speakers alot and did give much better lowend to than before. But what really shocked me was the sound of this amp driving my ET LFT-8B to output levels of my old amp. That amp had three times the output power of the Torii MKII, the Torii sounded better in every area and then some over the other amp, dynamics, speed , detail, soundstage, the space this amp gave around instruments was scary, the drums..... sounded like wood drums instead of tin cans. I know this setup won`t play levels that my hornshoppe horns will play, but boy...... did it sound great . Greg

Does anyone know if GZ37 could be used in place of GZ34 in these amps or a Taboo? Mullard GZ37 are easier to find and cheaper.

A couple comments I'd make about the Mullard EL34 reissues:

First, I tried a quad of these "reissues" to replace some original Mullard EL34's that I was very accustomed to hearing on a daily basis for a year, that I'd dearly loved the sound of.

Well, I held my breath thinking it was very likely I wouldn't care for the new ones, but was shocked at how similar the reissues sounded to the originals.

The one negative experience was the premature death of one of the new tubes within about a month (a sudden short that also blew a fuse).  

Hopefully that was just a fluke, and the overall reliability is good, because they are not particularly cheap.

Well, after a lot of testing the Winged Cs have won out over the Tungsol reissues, but not by much, I'll put the Tungsols back in in time and won't be very disappointed I wager.

Also, I've moved from cryo'd 6N1Ps to the 6N2Ps I was using in my CSP2.  I really prefer the tonal balance of the 6N2Ps, lusher, more analog like to my ears, even though you do get a headroom decrease.  I've ordered some 6N2P "R" version which is supposed to have twice the longevity, just to see if they make a difference. Should have a few pairs soon.
