Older 6SN7's are generally better. For the prices you mention, you should have no problem getting used Sylvania or RCA 6SN7GT/VT-231 on eBay. If you go with RCA get the grey-glass.
Best 6SN7 for the money?
Tube rolling on my Sonic Frontiers was enough to drive me insane with all the 6DJ8/6922 available out there. I now acquired a BAT VK-150 which uses 8 6SN7 per amp (16 total) and I can't possibly roll them all without going broke.
I have read on Agon discussion forum in the past the two front most tubes are more critical, that still leaves me 4 tubes to roll. I also read about Sylvania 6SN7 being a good NOS for the money, but there are so many different Sylvania out there and I don't know the difference.
So I am turning to the experienced Agon members to tell me which 6SN7 to go for, say about $20 to $30 a piece (or $50 to $60 per match pair). BAT owners, should I waste time and money and swap out other 6SN7 with something slightly better?
Thanks in advance.
