  Hello,
 
I was wondering if anyone has an opinion on a comparison between two sets of 6SN7 Drive tubes for the WA22.
 
- Shuguang treasure cv181-z
- Sylvania 6SN7GT NOS (woo audio 330$/pair recommended drive tubes)
 
I'm currently using my WA22 with Sophia Princess 274B mesh,  Sylvania 7236 1963, and stock drive tubes

More than the type/maufacturer the key is to get QUIET, matched tubes.  I've run through many pairs of various 6SN7's with my WA22 only to find one or more very noisey.  As straight forward as Woo maybe their prices for the "upgraded" tubes are outrageous and I do not believe they take the care necessary at their price point to warrant the expenditure.  Search the net, many bargains exist.  .

I agree Woo's prices are too high, those sylvania 6sn7gt's can be had for a fraction of their price, if you like the 6sn7's take a look at some sylvania's 6sn7wgta they can be had for as little as 30 or 40 per tube and sound really good..

Nope.  I have a dead Woo on my hands.  2nd fuse blew immediately.  Replaced all tubes with different tubes and changed power cords, 3rd fuse blew.  There's something wrong inside.  Time to send it in.

Sad to hear about your Woo interrupted.

Hope you get it repaired in time to swing
during year-end holidays.
 
Pulling for you in SoCal.

Glenn can help you out...looks like four interstage coupling caps.  PartsConnexion sells them/V-cap, not cheap though so be prepared to get wallet-hurt.  These take a loooong time to burn in.  Glenn probably recommends Duelund instead, not cheap either.
