  Ugh. Well thanks for confirming. I think I'll swap them out but keep the Sophia in and see how that combo sounds. I might be outside the return period; I'll have to check.

I stay away from Woo's "upgrade tube options" due to the fact that they definitely didn't sound "upgraded" to me. The only thing "upgraded" was their prices. I did "upgrade" (like most) to the SP-274B only to find the Brimar 5Z4G out performed it at a fraction of the price.

When I bought my WA6 second hand it came with a PSvane 274B, a Sophia Princess 274B, an old Potato masher 5R4G a pair of Sylvania 6DR7's and a pair of NOS RCA 6FD7's.  The PSvane lasted two trial listens and went straight to the internet.  They sounded terrible, grainy and lacked dynamics.  The new Sylvania's were probably Woo's original tubes and they had a fatal hum and they are now out for good.  The Brimar 5Z4G sounds equal to or better than the Princess 274B so the Princess is parked in my tube storage box.  When I looked at the prices Woo charges for the upgrades I took a pass.  You don't have to look far to find a similar pair for much less money.  This is no criticism of Woo, they are just trying to earn money. We are just trying to save some.

Agreed.
I prefer either the UE-596/Mullard GZ34 (which I need to buy) with either some 68FG's/6FD7 (big bottles) or 6SN7's.

Having one of those moments. The synergy between the Naim Uniti2, Woo WA6 SE, Cardas Clear and HD800 is a sin. Ergy.

Just got a Valvo GZ34 (black base) marked with F33 L1C and 164 on both sides (I wonder what year it is). Definitely sounds much much better than the stock tube from Woo.

The seller also has a NOS Siemens GZ34. Did anyone tested one of these in a WA6? I am tempted to buy it as a spare.

I had a NOS Mullard GZ34 in my first WA6 (sold) and need to buy another…I really liked the way it sounded. I should have kept it and sold my first WA6 with the SP-274B instead.

I would really like to get myself a W6SE very soon. Are tubed amps sensitive to vibrations, and will it affect the sound quality? I aske these questions because I am a seaman. Vibrations 24/7. Would greatly appreciate you guys' thoughts about this. Thanks.

Greetings all. New WA6 owner here.
I was wondering, how could I verify that my WA6 has the v-cap upgrade?

I just had a Woo WA6 that's off to a new owner.  Just looking at Woo's site, I don't see a capacitor upgrade option.  There are numerous tube options available.  This doesn't mean that It wasn't offered in the past. But to my recollection I don't recall that option.

It was once an option.
When I bought my WA6 (new) about 4yrs ago I asked if I could get the upgraded caps, but they no longer offered the upgrade at that time, so it would have to be an earlier model than mine, unless the upgrade was done by someone other than Woo?
