6L6WGC/5881 Tube choices for Amp


Dear Friends,
I have a small system in my office which punches out 40 Watts (sounds like 80 really) in pentode configuration.

I currently have the stock tubes on em - not bad, but i feel with the power tube change, things can go really sweet.

I have no knowledge on Tubes, Frankly on Ebay a quad matched pair
can range from 400-900.00 i do not know if its worth it to spend that
kind of money.

However,i am keen on changing the ECC83 to Brimar NOS.

Any help i can get is really appreciated!

You may find that your choice of input and driver tubes will affect the sound more than that of the power tubes. When I had a SE amp using 6L6/5881 tubes I found that the new issue Tung-Sol 5881 tubes had a very nice sound. Worth checking out but results may vary according to application.
Yes..Tes Rbrowne, Thanks a lot i couldn't find a better or NOS 12BH7 thats worthwhile, i am going to replace the ECC83 with Brimars..so the reason to look for a nice quad 6L6.
Have you looked at upscaleaudio.com or tubesandmore.com or even echohifi.com. Quads of these shouldn't break your bank. But yes I would spend extra on NOS. Each brand does have a personality.
The Problem is i do not know which quads are good for the money i am willing to spend - for me the rolling stops threre - so i want to go for something solid - hope someone can help me..
My Manley 200 mono's use eight 6l6GC/5881 each. Since purchasing the amps several years ago I have used NOS GE's, NOS Tungsol 5881's (expensive!), Sovtek's, and Svetlana Winged C. To my ears, and IN THESE AMPS, the GE's are excellent overall if slightly dry sounding, the Tungsol's are a beautiful sounding tube but ultimately too romantic and dark sounding, the Sovtek's are OK but dry sounding and a little glary. The Svetlana's are fantastic for the money (about $65 ea), and while a little brighter than the GE's, they are very smooth and overall on a par with the much more expensive GE's. A no brainer IMO. I hope this helps and good luck.
