Did anyone ever try KT88 with an adapter instead of the 6080?

Is it possible?

Is it possible?

Many do it on the Feliks Euforia which also uses 6SN7 and 6080.

KT88 need less current than 6080 at the same voltage.
You need an adapter with correct pin out and will Lose the warranty though.

However from my limited understanding it should work and I wanted to inquire if anyone ever tried it in here.

Maybe it doesn't play well with the output transformer and that's why it works on Euforia and nobody does it here.

I learned about this two days ago as well.

Tube amps are such a pain, if Woo does not give me the OK I would not risk it even if the math adds up

Woo most certainly won't give the ok on this.
I simply wanted to ask for experiences of those that tried it

Even Feliks doesn't give the ok but many used that setup for years without issues.
Learned about this in their thread and that spiked my interest, therefore I came asking here as well.

Man. Have upgraded to a pair of Sylvania 6SN7WGT tubes (pre-owned) and the sound went to another level with deeper bass and a more pleasing balanced sound. Love it!

But I get the occasional static on one side of my phones with one tube but once I pull it out and put it back in, it's fine. Maybe the tube will die on me... hopefully not.

Had the same with the same tubes. Only one of tubes were bad with a little bit of static. Bad luck that happens. But awesome tubes!!

I have been using some NOS Sylvania Brown Base driver tubes, which definitely sounded a lot better than the generic ones that came from Woo. Yesterday my pair of Black Treasures arrived and they sound fantastic. In many ways better than the Brown Base even. Certainly a different flavor than the Sylvania.

I have a Mullard rectifier (NOS) coming later in the week. Currently using a NOS JAN Phillips which was a nice improvement from the generic that Woo sent. Hoping for a similar difference as what I had comparing the Sylvania to the Black Treasures driver tubes!

So far the only power tubes I have are two pair of NOS JAN Phillips. I want to try a different power tube but I am not going to the expense of some of those out there at this time .

You may find that the Mullard rectifier tube has the most dramatic effect on the sound quality emanating from the WA22. When I put in an IEC/Mullard GZ34 to replace a brown base RCA 5R4UG in my WA6 first generation, the improvements were dramatic. I guess that everything begins with the purity/quality of the dc flowing through the circuitry...

Looking forward to trying it. I do know that going from the no name rectifier tube that Woo provided to the JAN Phillips was a nice improvement.

Hmmm, I was told the rectifier tube has the least effect on the sound, that is in comparison to the other tubes on the WA22.

@attmci "Keep your eyes on ECC35 and USAF-596 (need adaptor) which are still available at reasonable price". Where you seeing reasonable as the ECC35 RU1 and RU2 with brown base from the 50's and 60's current market range is $250.00 to $500.00 per single, unless you're referring to ECC35 RU4 with yellow lettering from 70's. Also the USAF-596 current market range is $225.00 to $300.00. Maybe reasonable equals something different for others

Threw in the Brimar CV1985 KB/ FB 1955 for good measure ...

Yeah I gave up on them, the prices are BS. You could get USAF for 120 ish USD a few years ago

 

[ksorota]

Wish those cv1985s were still around for 55$ a piece. Look to be around 300$ for a pair!

LOL...you gotta pay to play...literally...

Well I just recently purchased my WA22 (2nd Gen) and have purchased two different NOS tube sets for the drivers, two NOS set for the power tubes, and two different NOS rectifiers, not counting the tubes that came with the amp... that is a decent amount of tubes purchased in about a month. I think this is certainly enough to get started .

As I get into the Woo more I might end up picking up some more "special" tubes... from previous experience with other amplifiers I do believe the Black Treasures are definitely a great value for a really good sounding tube!

The only other tube device I currently use is my Hattor pre-amplifier and I rotate four different sets of tubes in it .
