Nice, are those RCA black glass I can see?

 
Yup, or I guess grey-glass is more accurate. WWII vintage, plus Brimars and SERPs. A warmer setup. When I get into a "I want more detail" mood I will throw on one of my various Sylvanias (brown-base 6SN7s or the VT-99s). Or perhaps a T-S VT-99, or Ken-Rad, or some Soviet tubes (Melz on the way), or...

Have you tried running TS RP (or NU) drivers?
 
I am currently running Brimars + SERPs + TS RP (6SL7)s. Sound is excellent from my WA5.

NU 6F8G doesn't work on the WA5. I have one pair of TS RP VT-99s but they sound just like the cheaper FP, of which I have a bunch more. TS RP 6SN7s are out of consideration due to price (and I'm not sold on it being a good idea to run 6SL7s/6C8Gs on a WA5).

6C8G NUs and TS RPs work great in my WA5. Some folks have had issues with the WA5-LE with 6C8Gs, so I understand your caution.

Just tried a pair of TS BG/RP 6SL7 in my WA5-LE last night. They worked fine and sounded really good but the gain is lower than the 6SN7 or 6F8G versions so I had to turn up the volume knob a little more to obtain the same output level.

Used a pair of Phillips 6dj8 using a pair of c6g7 adapters at Gibosi's suggestion below in the dubstep girl rectifier post which I copy/paste below.  The bass drums are more accoustic and there is less slam as the sound is over all leaner I like it for a change in the WA22.  I have also tried 6cg7 at Seamaster's suggestion - I like the rca blackplates.  I still need to acquire the ecc804 he suggested.  Thanks to both members for their suggestions.

ECC88/6DJ8 and premium versions: E88CC/6922 and E188CC/7308. (These require the same pin adapter as 6CG7 and ECC804).
 
E80CC/6085 and 13D3 (These require a 12AU7 pin-adapter)
 
And each of the following require different pin-adapters
 
E182CC/7119 and 5687
ECC40
6463
2C51
 
Happy rolling! :)

I've got those tubes running in my WA5 right now and noticed the same loss of volume. Sounds amazing, though.

Brimar 5z4 with ts 6c8 is sounding so clean.


You have taken my combo.

You can see the burn marks on the top of my 5Z4. I've been using it sooooooo much.
