  Hi JV,
 
Thanks for your answers - will skip the metal 6N7 tubes. There are Russian 6N7G equivalents called 6N7S - does anybody have any experience with these? (Can be found very inexpensive)
 
Or are the Coke Bottle tubes the only way to go?

 
Hello Mordy...
Have not tried the Russian 6N7S, but have tried all the styles (non soviet brands) and yes, Coke Bottle is the only way to go.

Hi mordy.
 
Your question has prompted me to finally make a long-held observation (already taken as gospel by many, I should imagine!!)...ie - I don't think it can be coincidence that SO MANY of the best-performing tubes turn out to be the ST shape "Coke Bottles"...viz ECC31/32/CV181; now the 6N7G (especially the gorgeous FDD20!); Chatham 6AS7G; Tung Sol 5998/WE 421A; GEC/Osram 6AS7G variants, etc. etc. etc. And they LOOK so much nicer too (in my eyes, anyway!

Time to raise the price. Seriously.

Feliks is a very small, family-owned company. Too many orders will sink them. I can go into all the reasons for it, if anyone cares. I'd strongly suggest putting on Elise's price on par with its Asian rivals or higher. It's either that or expand production. The latter is far more difficult to execute effectively.

Hey Guys,
 
Just a couple questions about 6F8G tubes.
 
Shows they are compatable.
 
1: Do I need an adaptor?
2: Any reviews? (How do they sound)
3: Best Manufacturer?
 
Thanks

Yes, a 6F8G to 6SN7 adapter is required. In terms of sound, most sound about the same as their 6SN7 counterparts. The main exception is the Nation Union. In my opinion, the NU 6F8G is better than the common black-glass NU 6SN7.
 
One advantage is 6F8G are often cheaper than 6SN7s. For example the BGRP Tung Sol. In my very personal opinion, the TS and NU 6F8G are the best. But I would encourage you to try other brands as well. 
 
Also, 6C8G are very similar, use the same adapter, and are often even cheaper.

  I think they look cool too. Just bought a pair with adaptors. For a guy that really didn't want to roll very much. I'm sure buying alot of different tubes and adaptors. I don't even get my amp till November!!

 
HA!!  I said the exact same thing before my Elise arrived.  And I too, bought several tubes before she arrived :)
 
It's FUN!!!
