Default suitable transformer for stereo aleph 5?

could you use this transformer for a stereo aleph 5?

http://www.partsexpress.com/pe/showd...D=123281&DID=7

i want to do an aleph 5 on a budget (my current aleph 2's are KILLING me in time and money... they are expensive). if i had enough heatsinking, would the extra voltage be an issue, and would this give me extra power?

You need a transformer like Avel's Y236900 25+25 800VA (you can order directly from AvelLindberg )

40+40 800VA after rectifiers and caps would provide approx 56V rails.
The schematics for the Aleph's indicate:
1.2's 60V
2's 45V
5's 34V

I don't recommend it.

Cowanrg,

I got these for my Aleph5 from Victoria Magnetics in Georgia.

You can get a good deal if he has them in stock but he'll do specials as well.

I got a deal at about $65 each 'cause he someone renege on a deal. They have the copper shield as well. Full price is a few bucks more but you don't know what he has until you call him. Also checkout the leftover info in the WIKI bulk purchase.

Plitron has excellent transformers at 500VA (suitable if well ventillated), 625VA, 750VA, etc. Very beefy compared to other toroids. Cost is reasonable--actually very reasonable considering the build quality. The only possible hangup is that you may need to wait a few weeks; they seem to wind them according to orders on hand.

ive checked into plitron, and im using those for my big aleph2's, but they are too pricey for a small scale project... they are definately nice, but budget does not come to mind when thinking of plitron.
