My Dream Aleph 2 Coming True

JPDuarte · 06:13 AM

Hello everybody of this wonderful forum, I started this project more or less 6 years ago and then stop suddenly , now I don't see the day that I finish it but I know is very close, but have some simple questions to finish it. Trans are Antek 1000v 2 x 37 secondaries and 6 x 68000uf caps. 1- Is 2.00mH 14 gauge fine ? Trans primaries has a pair of cable with 115 w red-black red-black , that means only one pair is to be use red-black. Sorry for this newbies questions but need to be 100 % sure. Thanks in advance. I'll post some photos through the entire building process. Thanks in advance. JP Duarte.

2mH , 14 Gauge ; what's Rdc of choke ?

you must use two 115V primaries in parallel , to have 1000VA power ;
be sure to connect them in phase

why text in bold ?

besides that - I hope that you are living in country with adequate mains voltage ( 115Vac ) ?

From my coil calculator, it will be around .3 ohms.

Thanks both of you for your response, but when you say in parallel that means connecting both hot wires ( red-red) through AC inlet and both neutral wires (black-black) to the cold connector of Ac inlet, please clarify a bit about phase. Thanks again. JP Duarte

it's easier to give us link to exact xformer datasheet on Antek's

Hi JP,

That depends where where you are geographically

Bill Fuss · 6th October 2010, 12:42 PM

I've used quite a few Anteks. For 115V operation, connect red together and black together on the primaries.

Lately I have found the Anteks secondaries are not very well balanced, dual bridges are a necessity to keep them quiet.
