Default Is this Transformer OK to use with BrianGT's dual mono kit?

http://www.partsexpress.com/pe/showd...number=122-640

AVEL Y236750 330VA 25V+25V TOROIDAL TRANSFORMER

Should I get something larger, or will I need a different type for a dual mono gainclone kit?

Thanks,
Matt

I used one of these to power two channels. A pair of Y236503 160VA 22V+22V's might be better for dual mono.

Earlier during this kit's creation, there seemed to be a general consensus that <25V per secondary was ideal. At least that's the idea I got.

25vac is fine for the secondary voltage. The 2x22vac 160va transformer would work fine for monoblocks as well. The 320va transformer is overkill for one channel, but allows the option for reconfiguration at a later time if you decide to bi-amp your speakers, instead of using single channel monoblocks. I have heard that bi-amping works great with these amps.
