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!

Dear Frogman,
Thank you so much how much do you think a Winged C Svetlana
quad will run me for? - and where can i get it? are the 6L6WGC or just 6L6GC?
I would imagine that you can probably do a little better price wise if you shop around, but as far getting tubes that are the real thing goes, as well as great advise from Kevin, this is what I would do:

Thegoodarcher,
You should read Jeff Day's (writes for Positive Feedback, also 6 Moons) blog at Wordpress, concerning 6L6s, Jeff did a tube shoot-out in his Leben 600; the 6L6 that won out was the NOS Reflector 6n3ce. They can still be gotten. Jim McShane was selling them for about $65.00 per quad. McShane is out of stock. I use these tubes in my Primaluna Dialogue One. Terrific tube. Inexpensive, but will last for years and sound great. Look around the Internet. I believe I saw them recently from reputable sellers. I do have spares, but not selling them currently. Good luck, hope this helps. Check out Cyroset tubes on Internet. Again, best.
P.S. Kevin Deal at Upscale can usually help with the SED Winged C, but they are more expensive. A couple of other good sources: Brent Jesse or Andy at Vintage Tube.
