Has anyone tried using 12AU7 or 12 AT7 variants in the place of the 6NiP input tubes?

I asked Schiit and the person who replied just quoted from the manual that they could recommend nothing but 6DJ8/6922 variants.

I ask because I have a hybrid amp which uses 9 pin input tubes. I can use any 6DJ8, 12AU7, 12AV7,12AT7, 12AX7 variants. My favorites for this amp are GE 5 star 6829s, Raytheon blackplate 6414s, and Amperex 7062s.

Regardless of whether or not you believe that cryogenic treatment of tubes helps them or not, I must extend customer service kudos to Cryoset/RonSheldon. I ordered a set of 6N6P tubes from them on Friday, 4/27 and received them in today's mail, Monday 4/30, without paying any extra shipping charges. That's sending them from California to New Jersey pretty damned quickly.

Hey guys,
I'm a relatively new Valhalla 2 owner. Driving it with a Bifrost.
I just wanted to say thanks for all the great posts in this thread.
I was able to make some guesses as to what I might like to try to I ordered the following from thetubestore.com:

Electro-Harmonix 6CG7 / 6FQ7
Genalex - Gold Lion E88CC / 6922
JSC Voskhod 6N1P-EB

Paid the $5/tube to have them balanced/matched. Not sure if this is required. Do you guys typically go for the matched option, seems it would make sense for this amp, just not sure if it's required.

Thanks,
Erikson

Congrats on the purchase, I’m considering getting the Gold Lions down the road as well.... for the time being, I am also enjoying the Bifrost and Valhalla 2 combo... but using the JJ E88cc for now...bit cheaper than the gold lions, hehehe, but I’m quite happy...

from the tubestore’s Faq they say it’s not needed for preamp tubes.... but the power tubes require matching..

cheers!

Are you using any of these to replace the 6N6P power tubes?

 

[Erikson2k]

Yeah I believe the Electro-Harmonix 6CG7 / 6FQ7 are power tubes.

Uh, Guys. None of those tubes can be used as power tubes in the Valhalla.

They can all be used as input tubes. The 6cg7 draws 600milliamps and can be used as input tubes on Lyr1 and Valhalla 2 only

Edited for grammar

To be honest, that's what I thought ... I have yet to find any substitute for the 6N6 power tube.

I don't think there is one. There were two manufacturers of the 6N6. Novosibirsk and another, whose name escapes me

Thanks for clarification. I was thinking the height of the tube was indicative of it's purpose. If you Google image search the "Electro-Harmonix 6CG7 / 6FQ7" it looks like the same shape as the 6N6P.

For power tubes, nos Fotons sounds good. Not that much change is sound with them power tubes.

After reading some good reviews about WE 396A and TungSol 2C51 I went for the TungSol.
Today I recieved them and I'm quite happy with the sound! Female voices dont hurt anymore (they did with my JJ gold pins (E88C)) and I feel like I can listen for hours now!

Did you need adapters for those? Also what headphones are you using?
