im going to run 2 miniA's for my mids/highs. I figured i could use a little extra bias for my BG neo8/neo3 @4ohms

i planned to use matched fets, because when i get time ill prolly step up to a Aleph30 for the neo8.

i still have a AlephX in the plans, and matched fets are a must!

i have some PSU caps 12000uf 50v nichicons snap ins. i dont have the budget for computer grades so ill just CRCRCRCRC the crap out off my supply!

You only have to match the input fet's The output fets on a mini a ( 2 fets ) do not have to be matched it will not makea difference at all in sound.

I'm moving into a house in amonth so i will be starting projects again speaker enclosures and building my amplifier chassis's.

Excited to build my aleph stereo blocks.

this was posted over in the chipamp forum, i figured some people might want to look at this.

if i guess right 117vac input 44v ct would be 30volt rectified, lose 3-4 v drop under load, and then a healthy CRCRC filter = a nice regulated 25v. perfect for a A30.

with UPS i got a shipping estimate of $11.00 + $33.50 seems to be a good deal for me. can i get a better deal ($44.50) for a 500va+ toroid shipped anywhere else?

i had been looking at the Antek transformers on ebay.....

just looking into my options.... right now i have some 12v 17ah batteries to run my miniA amps.



Look Transformers
