Has anyone tried the ECC32 with 6080/6AS7 tubes on the WA22 before? I would try, but the amp gets really hot with those power tubes, and I'm reluctant to plug in the current-hungry ECC32s.

On the 596 right now, which is slightly cooler than the GZ series. I'm just worried that the 50% higher current of the ECC32 plus the heat from the 6080/6AS7 might stress out the transformer.

I guess as long as it's in the compatibility list it should be fine. I'll give it a try after I'm back from F1 qualifying tomorrow.

Electrically, operating a 596 is the same as operating a 5U4G.  The 596 is basically a 5U4G fortified for aviation duty.

Hi kchew,

I am hoping to receive my WA22 next week.

Am already looking to roll the tubes, saw a pair of NOS GEC U52 rectifier tube....tempted but is really expensive. Where do you go to get your tubes?

I am hoping to find tall and sexy looking coke bottle type rectifier & power tubes.

Finally had time to roll in some other tubes in Clayton's WA2 and I have to say it improved quite a bit
 
I took out the 5998s and replaced them by simple RCA 6AS7G, giving them a slightly warmer sound
I got a new pair of 6922 Sylvania, smoother sounding as the 7308 Siemens I had before
As rectifiers I'm using a pair of Philips Miniwatt
 
So I finally succeeded in making it sound warmer and more "bassy"
Happy loaner!
 
Btw Clayton, when I give you back the WA2, does that mean I also get chocolates and beer from the States? :D Just kidding :wink:

That's great. I see that you got the WA2 to perform to your excellent standards. Now which headphones are the best with your the new improved WA2?
 
Well, that gives me about a year to find those great Chocolates from the States. Forget the beer from here. I'll pay for an all-you-can-drink evening at In de Wilderman. :wink:
 
This is the beer I had in Vondelpark. I liked it. But really, any beer would have been great on that hot August day in the park.

To be honest, most of my tubes came from ebay, but some came from vacuumtubes.net
 
For the rectifier, perhaps you can start off with the Mullard CV378, which is $120 at Well Audio at Burlington Square. If the U52 is electrically equivalent to the 5U4G, then the normal Tung Sol or RCA 5U4Gs can be a good starting alternative.

With the WA2 I have mostly been using the LCD2 Rev 1 and the HD650. The HD700 is soso with the W2, I prefer it on the Crack.
