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 appliction.

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!
