Anyone try a U18/20 rectifier?  Requires a 5u4g adapter.

Its a 4V rectifier and can't be used in place of a 5 V rectifier without making allowance for that.

Is anybody know if an 5z3 to 5U4 adapter is the same as 83 to 5U4 adapter?
Have you ever tried 83 rectifier (on WA6SE)?
Thanks

I picked this Brimar 5V4G up last week and I gotta say for an inexpensive tube this one is without a doubt one of the best sounding 5V4G I own, It's almost as good as the mullard GZ32 which is one of my favorite rectifiers.  I've noticed all 5V4G's make excellent sounding rectifiers with maybe the exception of the Sylvania don't really care for that one it sounds hollow almost like your in a tunnel. The Brimar 5V4G is well worth a try glad I found this one it's really excellent..

Hi, for WE422a, is there any difference in performance among those made in different years? As far as I know, there are three versions: those with round getters; those with square getters and black plate; and finaly the earliest with square getters and grey plate. Thanks.

My opinion is the Grey plate is a little better sounding

Here's an interesting rectifier I found at least for me it is, a NU 5Z4 metal tube, I was pleasantly surprised how well this 7.00 tube sounds it's well worth a listen..

Wanted to add that i measured the tubes heat level at 330 F in my WA22 was concerned and contacted Woo they said no problem ,always nice to here.

Pin out mainly I think.  An adapter is needed for 274a for WA22.

274A is a 4pin tube and the 274B is a 8pin octal tube the tubes are the same except the base.
