Yes... I understand from reading the past threads that the pseudo power supply mod makes a significant difference... I'm just not confident enough with my limited circuit knowledge to take on the task myself!

You ain't heard nothin' yet! Just wait!

As the break-in hours accumulate on my WA6(w/BG&V-Caps), I am finding it harder to hear much of a difference between rectifier tubes when tube rolling. In the first few hundred hours of break-in, I could easily discern differences between all the different tube variations, with the metal base...

My WA6 was the first to be built with the Black Gates & V-Caps (per Jamato8's recommendation). My amp has about 500 hours on it now. I just completed about 100 hours burn-in on my new SAA Equinox LE cable and I must say, this amp has amazing clarity/resolution. I have been in the audio hobby for...

Has anybody tried a Western Electric 422a Full Wave Rectifier in their WA6? I am interested in how this tube sounds compared to the GZ34 Metal Base. Western Electric 422a (5U4GB)

Quote: Originally Posted by takezo The bass is not as tight and focused, as expected of a new part... The soundstage, width and depth is smaller than what the stock caps provided with burn in... Hey takezo! Welcome to the WA6 Upgrade Club! Don't worry about the bass! Mine was...

Anyone here ever try one of these? Groove Tubes 5AR4 Solid State Replacement Module "Replace your tube rectifier with a solid state module. A great module for giving your tube amp a little boost. This little gem will increase response and add a bit more punch by providing more power to the...

My "Audiophile Edition" WA6 was delivered late Friday afternoon. I was amazed at the weight of the package, and after unboxing, was surprised by the size/heft of this amp, which is actually a little larger & heavier than it appears (to me) in pictures. The transformer on this amp is massive...

mochimon, I see that you like Piano. You might want to read this review of the Woo Audio WA6 which was written by a Pianist (30 years). As you know, the Piano is one of the most difficult instruments to get right in audio reproduction and no one knows as much about how a Piano is suppose to...

Well... Jack must have been impressed with my custom build WA6 w/Blackgates & V-Caps as I notice that he now offers these upgrades on his Website. Even shows a photo of my amps innards. Link here > http://www.wooaudio.com/products/wa6.html
