Need some help hooking up old trafo

[PJN]

Hi Guys,

I'm trying to use an old transformer from dead marantz receiver to power a dual mono chipamp.com psu boards. It outputs +/- 24.5 vac, but I can't figure out where to hook the ground to. The PSU boards that I have only have hookups for AC+ and AC-. I've attached a pic of the trafo wiring and a pic of the PSU board.

Thanks for your help.

I see the AC1 and AC2 on the psu board, but do you have a schematic you can upload?

First there is a mistake in my hand sketch, there are two grounds, one for each V+ and V- out. I'm thinking that the bar across the top of the AC+ and AC- on the inside of the board might be nomenclature for the ground, I do have the PDF assembly manual, but there is no mention of what it means or where to hook up the ground. I've attached pics of the schematic and a pic from the website. the website pic is unclear as to where to hook up the ground also.

Noted, but I wasn't going to use that sketch anyway so I let it go.

Yes, that would seem to be correct. The bar is something made up. It's not a standard nomenclature. Boole may turn over, but at least you can finish the power connection.
