Have you decided on power tubes?

My experience is that they can make a bigger difference than the smaller tubes.  You can fine-tune your sound quality by mixing different qualities in the power tubes and the driver tubes.

FULL DISCLOSURE:  I occasionally sell tubes from my personal collection.  I can post a listing here if I have something that interests you.

I have several power tube options available, again depending upon your budget.

The premium European 12AU7s will likely be above your $30-$40 each budget.  The US options should be well below that.


 My experience is the opposite, the driver Tubes tend to make more difference when I’ve tried them. 
I have New issue Gold Lion KT-88’s that I bought for my Jolida amp. They have may 100 hrs on them. My understanding was also the driver tubes voice the amp the most. I was under the impression the output tubes have minimal sonic  effect. Once I get them built, I may hit you up. I won’t receive them until Thursday. Thank you for sharing. 
The Gold Lions are nice.

I have quads of GE, RCA, and Ken-Rad domestic and 2 different styles of RFT Germany 12AU7s that are under your budget.

I have some Sylvania and Raytheon pairs and trios, but no matched quads that would also be well below your budget.

My Amperex/Valvo/Mullard/Siemens/Tungsram varieties aren't going anywhere anytime soon.  ;~)

Enjoy.
