Hi All,
Pardon the newb question. I have googled this to death and cannot find a straight answer. I would like to build an ACA using a Hafler P1500 as a donor chassis and start of a power supply. The transformers in the Hafler appear to be high quality, and I'd really like to be able to use them for a premium ACA build. The transformers have dual CT windings (40-0-40 and 80-0-80). I've read that you can wire the windings of some transformers in series to double the current and keep the voltage the same. Essentially, I'm looking for a way to use the 40-0-40 winding to produce 20VAC leading to 24vdc for the ACA boards. I had planned on using SLB single rail power supply boards to power the ACA boards in a true dual mono setup. Can someone explain in elementary school terms the simplest way for me to achieve 24vdc with these trannies? Thank you all! --Jaybird

nope, no way, as is
but, if you wire its primary to 230Vac and you're in 115Vac area, so result is having 20-0-20 at secs, you'll end up with something useful - roughly 25-28Vdc ...... price being resulting 50% of normal xformer VA
though, still enough for purpose
ballpark for ACA
clarify where are you living, and do you have so called dual primary xformer (is it possible to arrange it for 115 or 230Vac)

Dang, unfortunately only 120vac primary for input. Living in Texas, USA so 120v service. Any other method I can concoct to drop the voltage to acceptable levels for an ACA? Thanks for the input, Zen Mod.
oh yeah, quite possible!
remove xformer from case
wrap it in some cardboard, to be cushy and protected
wait to see a Postman close enough to your place
carefully aim, toss cushy xformer in general Postman's direction (no particular intention to really harm poor bstrd)
when he jumps scared, running away , just hope he did left Bag with cash behind
take few hundreds from Bag, arrange new proper PSU for ACA
