While I wait for my iron to be wound, I was able to hunt down today
this couple of tubes.What do you guys think? There are plenty more... should I buy
more Sylvanias or GE?
Best Regards
Follow Ups:
I agree with what Jimmy and Robert said. Go with Sylvanias if you want/have to go GTBs.
And go with GE...
The GE is an okay tube, not bad for the price, but not a great tube by 6SN7 standards either. The choice between the coin-base and the GE is a no-brainer: never ever take the coin-base over any other 6SN7. I think this is what Robert was saying, and if so I fully agree.Here's ten 6SN7s I'd recommend(in no particular order):
Tung Sol round plate 6SN7GT/VT-231
Sylvania 6SN7W (any of the three versions)
Brimar 6SN7GTY/CV1988
Sylvania VT-231/6SN7GT
Ken Rad VT-231 (black or clear glass)
National Union Gray Glass
National Union Black Glass
Raytheon VT-231/6SN7GT
RCA 6SN7GT/VT-231 gray glass
Telefunken 6SN7GTA (I don't care if these are "real" or not, but they sound nice).
Len,What? No brown based Raytheon JAN-6SN7WGT? GE and Sylvania 6SN7GTA aren't too bad, either (black plates, of course).
Yes, Raytheon early VT-231 brown base- good tube.
Hehe. The list gets pretty long, so I chose my top ten. The Raytheon and Sylvania WGT are nice tubes as are the Syl GTAs along with CBS/Hytron 6SN7GT, Tung Sol GTB tallboys, et al.
They were saying don't buy the 1970's coin base crap. The Sylvanias from the 1960's 1950's and 1940's are good tubes. The ones from the 1940s to early 1950s are amoung the best.
Thanks a lot. This piece of advise will make me save a lot of money
and effort.
Get non-coin base Sylvania 6SN7GTA or GTB with 'chrome tops', shiney black plates mounted on an angle & the clear micas. Good tubes that produce neutral (uncolored) sonics at reasonable prices. I believe the clear mica were produced to 1955-56 era.
The ones on the left - the coin base - are horrible, worse than the infamous Sovtek. Worst 6SN7 ever made. The ones on the right look like early 60's O-getter GE - not bad, not the best - I prefer Sylvania GTB's from this era if it has to be a GTB.
Well I will use them as testing tubes then!
It is educational to have average to poor tubes around to compare.
Robert,What 6SN7's Do you prefer. I'm currently using a Sylvania GTA in my pre and I am enjoying it but I'm new to tube rolling. Anything you would suggest and why. Any thoughts would be appreciated.
Sylvania 6SN7GTA are great - especially if pre-1960's. Very good value.A lot of people tend to be snobbish about some 6SN7's that aren't hyped & overpriced, but to me, there are lots of very good sounding bargain 6SN7's still available - 50's to mid 60's Sylvania GTB's are pretty good, pre-1960 GE GTB's are perfectly fine, 1950's GE 6SN7GTA's are simply killer, and if you can find them - 1950's RCA side getter GTA's are also very good.
Robert,Thanks for the post. I really am enjoying my system with the 6SN7 pre in it. It took it to a whole new level. Its' the first piece of equipment I have put in my system and new it was perfect from the start. BTW, is there a way to determine if the Syl 6SN7 is pre 1960. Thanks for your help and time.
