Dennis Had Inspire Amps

[Bombadil]

Speaking of Pope 6SN7 tubes, someone is offering a pair on Agon for $600!!! My goodness! They would have to sound extremely good.

[FloridaBoy]

That's funny! They are excellent tubes but not $600.

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.

Same folks. h_salience is the seller id. The UK version is very transparent and open sounding. All the Chinese CV181's are good tubes just different 'flavors'. I just searched their fleabay store and they only have pairs of the UK version.
Can you get a single tube on Amazon?

I'm near Ft. Myers.

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.

The new GL GZ34 is also very good.

IMHO, using the right rectifier..the one that delivers the right amount of B+ voltage for a given tube to sound 'right' in your system is more important than the brand.

You should get another quad of the 6P3S-E. That appears to be your favorite power tube. The good ones are getting hard to come by.

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

[Bombadil]

I haven't popped for any 6P3S-e tubes. Have read mixed reviews of them, most of them positive but not all. 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

Cheap enough, maybe I should try them.

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.

Perhaps the 6SN7 is a GT version, like this one....



And yes, the 5Y3 and 80 rectifiers are supposedly electrically identical, but Dennis and I found that even though the distortion curves didn't necessarily change much, we were able to notice a significant sonic difference between rectifiers.

Sovtek 5881 WXT | 6l6 WGC | 6

I bought a quad years ago from Jim Mc Shane and sent two of them to Musica. They are a coin base tube and good ones are getting hard to find.

Search both 6P3S-e and 5881WXT you'll see the difference. I have no clue who a good seller is now. I just looked at both on fleabay and it is confusing. The military one are from the 70's-80's and have a gold grid.
