Looked on the auction site and found a previous seller that went by Salience HiFi but no recent activity. Quick google search turned up the Amazon web store. Looks like they may have moved there business from the auction site.

If so, I am gonna order one of the UK CV181 to try on my 45 SET.

PS: Still in FL? Im over on the Treasure Coast myself.

I can (I think) hear differences when I switch between 5Y3, 5V4, 5U4G/274B, 5U4GB (I think I hear a tiny difference between this and 5U4G, but wouldn't bet money on it in a blind comparison), and GZ34. But within rectifier tube types, say a vintage Sylvania 5U4G vs a vintage RCA 5U4G vs Tubestore Preferred 274B, I am not convinced I can hear any differences. Many tube amp owners say the same. So I've decided to not spend a lot of money on rectifier tubes. Dennis has told me that he considers the low cost JJ GZ34 to be very good.

Try the amp with an 80, Sylvi GTA (bottom flashed getter is preferable) and the 6V6Gs. I might also dig up a 5Y3 rectifier...

Do you mean a Sylvania GTA (bottom flash getter ) 80?

I thought all the following I had listed are equivalent to the 5Y3 you suggest, except these are 4-Pin (I use them w/adapter) and the 5Y3 is Octal:

NOS RCA Radiotron 80
NOS Sylvania 80
NOS RCA Victor 80
NOS RCA Cunningham 80
NOS JAN Sylvania 80

Is there something I'm missing? Thanks for the feedback.

Tube Amp Doctor says that today's Sovtek 6L6WGC is the same tube and that they substitute one for the other depending upon what they have in stock. Others say the 6L6WGC is the standard 6P3S, while the 5881WXT is the 6P3Se. Confusing.

Here is a good guide to the various versions
Sovtek 5881 WXT | 6l6 WGC | 6

Cheap enough, maybe I should try them.
