Question Is 400VA enough for an Aleph30?

I bought 2 Antek 22v+22v 400VA trafo's on Ebay. Can I get away with just using one for a stereo Aleph30 or do I need both? Will 400va limit the amps performance?

I guess I'm asking, how much transformer is needed here?

Thank you,

-David

You can use it. It may have a little more mechanical hum and get a little warmer than using two.

I would, if only for the ability to avoid ground loops by having
separate grounds for the two channels.

Do you use two in your amps or one with separate secondaries (4 sets for a 2 channel) ?

The thread just hooked my attention.

I currently own the same type of transformer 2x22V 400VA but I never thought to try use them in an Aleph 30/Aleph 3, because I knew that voltage was supposed to be 25V DC .That if I read correctly the manual

Anyone so kind to advise ?

From my point of view 22x1.41=~31 V

Too much for Aleph3 but slightly less for Aleph 5

Am I so lucky to find some use for those babies ?

Thank you
