I have both now in my hands, EML hands down is the Best rectifier i've tried, the bass response, the dynamics, air between the notes and the soundstage is just awesome ! Sophia is somewhat bright in comparison, bass is weaker and dynamics are also weaker

I should have mine in my hands tomorrow.  Was planning to do a writeup on them and the Sylvania Bad Boys at some point.


You also can order from Jac Music, they offer 30 days and 1 year warranty as option.

Guys I saw some 6SN7 to 6N1P adapters on ebay. Do you think the 6NS7 will work on my WA3+? I know I'll have to build a tube extender for the adapter as the adapter is most likley too big for the tube input on my amp.
 
I currently use 6N1P tubes on the WA3+ and they are fully functional.

The 6N1P is not a direct replacement for 6DJ8/6922, so I would be very doubtful.  Perhaps email Jack Wu and get his take, but personally, I wouldn't risk my amp on that one.

It's not a direct replacement? I see lots of sites saying it's a direct replacement, even the seller on ebay said it was.
 
Hrm... this doesn't make me feel good at all..

The 6N1P is most definitely not a direct replacement.  It is often labeled so by sellers not knowing any better because it often works in circuits designed for the 6DJ8/6922.  However, the 6N1P has twice the filament current than the 6DJ8.

I knew about the extra current heat already, but the seller on ebay said my amp should be able fine with the tube. 
 
Man not fun at all... Should I request a refund?

That's up to you.  If you feel like you were mislead and won't ever use the tube again, then probably.  However, if you are going to keep using the tube because you're ok with extra current draw, then probably not.
 
The confusion with the 6N1P is that the 6N11 is more closely related to the 6DJ8.  But, lots of sellers don't know what they're doing or are intentionally misleading people just to make a sale.

I think I'll return all four tubes to the seller.. but he's in Russia :frowning2:

The post to get them back to the motherland might be too expensive.  Maybe just list them in the F/S forum or keep them as souvenirs. 
 
Before doing anything, perhaps ask Jack Wu if the W3 can handle the extra load of these tubes.  It may.  Nonetheless, it's not a direct replacement even if it does work.

There's a discussion over on Tube Asylum about a couple of Russian 6922 equivalents - the 6N1P and the 6N23P. The 1P is extraordinarily cheap, and many folks speak very highly of it. It is not as directly compatible as the 23P, but I wrote to Jack and he says the 1P is a direct replacement for the 6922 / 6DJ8 in the WA2.

The one caveat is to make sure to get the "EV" version of whichever tube you want.

In Cyrillic, it's 6H1[P] - EB. (IIRC, the Russian P looks like an H with the crossbar at the top instead of in the middle...)

I've seen them for around $2.00 on Russian tube sites, which are a bit of an adventure, but I've had good luck so far.


I sounds like Jack says it's okay for the 6N1P in the WA2--however; I don't know about the WA3+.

The 6N23P is pretty close to the 6DJ8.  The 6N11 is the most direct replacement.  The 6N1P is a different beast, but does work in many circuits designed around the 6DJ8.  I'd email Jack directly to get his take.

I e-mailed him earlier so hopefully he'll say yes it's compatible.

UPDATE:
Jack said the WA3+ can use 6N1P tube no problem!!
