Another surprise as I listened to the 6GU7 for the last 2 hours. Everything I like about the 6CG7 is there with a bit less soundstage but just as great on vocals. Randy Crawford's 'Rainy nights in Georgia' sounded just so lovely.

Thanks HeatFan for sending me these lovely tubes to try. PM me your address I want to send you something for Christmas.

Agreed! A BIG note of thanks to HF!

I like the 6GU7 quite a bit. It sounds relatively open, more resolving than I expected, good extension all a round, fairly clear mids. I've actually ordered NOS equivalents of both tubes. A NOS Sylvania 6CG7 has been burning in for a few days and sounding better and better. Still more on the mellow side of neutral and a bit rolled-off on top, but very nice with the right tube in the back. This, compared to what I just posted about the TS rectifier in the Elise thread. You'll see what I mean.

A couple more substitutions are coming. I'll post more, once I can hear them.

We've discovered some good ones...The 6BC8, 6BS8 and 6BK7B really surprised me.  Not only compatibility but they sound good.
 
6SN7W came out to play tonight UT!....lol

I recall a beginner question in economics, "Why do we have better oranges in NY, on a more consistent basis, than in Florida where they're grown?" It's because one has to buy the oranges a ticket to get to NY from Florida, so it makes most sense to ship the better fruit. Your case is very similar; you have to buy a tube a relatively expensive ticket, so on a relative level it's most effective to purchase the best tube you can. Hope that made sense. :)

That's the one HF. Look after it well. :) The price for that new on eBay is a shocker.
 
Precisely Shaffer. High shipping cost is the reason why I'm selective on the tubes I buy. I haven't push the button on those tubes and probably won't.

A batch of 7N7 adapters finally made it to my mailbox this morning. Finally, I can audition 7N7 and 7AF7 in the DV. ATM, a DV is shod with a medium bottle JAN 7N7 and a JAN Chatham 6AS7G. The sound is very clear, significantly more transparent and delineated. The bass is the tightest I've heard yet from this amp. This being said, it's not a euphoric-sounding tube; it's more reflective of the source.

That's great Shaff!  The best part of the 7N7s is their clarity and detail, imo.  Was trying a ..GT VT-231 earlier.  Very fun tube.....Have to burn it in a lot more though.
 
I will join you later with a 7N7.  Have a Delco branded I have not listened to in a while.
 
But first, another Sylvania combo wanted to play..lol
 
Still with the Sylvania 6AS7GA....His partner now is a Sylvania Gold 5670.  Shorty can rock it indeed!!!

So what adapters do you know will work with the WA2 (e.g. 6SN7, 5670/ 396A ..?)  I would like to order most of them all-at-once from the ebay provider you gave me.

For the WA2 I have purchased three adapters (6SN7 to 6922)(5687 to 6922)(5670/2c51/396A to 6922).  I already had a small collection of those tubes that I use in other amps, so did some research and emailed various sellers on adapters then pulled the trigger.  The inexpensive drivers are drop-in replacements, no adapters needed.
 
 
DV & WA2 driver tube love:
