Bill I have and use both...The mixer is the best mixer I have owned, features and quality...and i have own a bunch, including Mackie , Toa, Boss, Peavey, Behringer , and Alesis..
My BA330 has worked flawlessly..and I have it on hand for every thing...In the studio for a quick mixer/ monitor, on stage , either as a primary sound or a stage monitor and it's mixer and effects...
The BA330 is the absolute "swiss knife) mixer/amp...
Bill why not just replace the power supply, maybe it is only the connection into the supply unit..
The Edirol mixer is worth it's price just for the room control feature...but the other goodies , insert effects, and master effects, are top shelf...
I was offered a large profit for my Edirol , and I refused, they are hard to find now...
The BA330 was never on my to sell list...I would buy it again if someone stole it...same with the Edirol...
The room control..I set it up for all my sound system/venues that I work...There are 12 memory locations...
I analyze the room and it maintains the quality, sound...
My favorite sound system has been my Roland Cube 100, for the last 27 years...This feature of the Edirol degrees the Roland amps to perfection...I will match this combo to anything you want to compare....I never , ever need a sub woofer and all three way sound sources work great ..nothing is missing like the Bose for example..
The Edirol mixer was the best update for my antiques...and the added gain makes the Cube 100's as punchy as anything on the market...besides I have 4 of these if I ever need it...

Let me follow up about the BA330,, I have since sold the Podium 802's (pair) and the Yorkville 300k, because the BA330 does their job and more ..The BA330 mixer /amp gives me the effects missing on the Yorkville, and mixing and effects missing on the 802's...I have the full range covered between the BA330 and Roland Cube 100's...I lack nothing..
