The 6SE is wonderful amplifier, if you don't want to get any trouble or you want to avoid any trouble to be happened during the mod, the $450 is worth to pay although I paid less than that for many of the caps in BlackGate NH. I was in trouble when the first time I attempted the mod but fortunately I have some helping hands from peanuthead, indydieselnut and of course Jack of Woo Audio, I have the problem solved finally and I was frightened to do the mod for awhile but it finally done.
I love my WA6SE.
I had the money to get my WA6SE maxxed, so I figured less risk and no extra time for brake-in. Yes I would save some money by doing it myself, but what if.
