So right off the bat I am ordering a pair of RCA 807 with tube adapers, 6P3S-E from Russia, Tungsol 6L6G (new), Genalex 6V6GT (new), TAD 6L6wgc-str (new), Sylvania 6L6 metal, 3 pairs of 6F6 metals (RCA, GE and Sylvania), Sylvania 6F6g grey plates, Sophia Electric blue glass 6SL7.
I am not too sure what to do when it comes to rectifiers, so I am ordering a new EH 5U4GB which Dennis sometimes ships amps with. What would you guys recommend as far as 5Y3 tubes and 5U4 both NOS or reissue are concerned? What have you experimented with? 5Y3GT?
Also 2 quick questions:
-can I use a 6SN7 as driver tube?
-274b with 807's or 5U4/5U4G?
Happy listening to everyone and Happy Holidays!!

I have a PSE and just received a Sophia Blue 6SL7. Excellent tube. Let us know how you like it.
I have a JJ 5Y3s on the way. A 6SN7 has less gain than a 6SL7. You can use a 5U4 or 274B with the 807's. Check out the Preferred Series 274B from the Tube Store. If you buy old production 5Y3's on epay be sure the sections are closely matched.
I have used the TS and GL 6V6GT but much prefer the Philips/Pope 6V6GT. I'm using quad of the Pope's with the Blue Sophia and a 5Y3 rectifier. YMMV.
You can use any rectifier with the TAD & TS 6L6. Experiment and trust your ears.
Look up your amp on epay completed purchases. There is a jpg of the rectifier/power tube combos there.
The old production 6L6G, GA's and 6V6G's can be magical. Use only a 5y3 rectifier with these.
The GLKT77's take up to 100 hours to settle in so be patient.
Go slow with tube rolling or you will go broke and nuts. Been there done that.
