Astrocade ac adapter

Archived from groups: rec.games.video.classic (More info?)

So, the AC adapter on my Bally Astrocade has given up the ghost.
Unfortunaly, the thing has pretty complex output, 4 pins with the
following voltages (to each other, all AC)

Anyway, it would be pretty tricky, although possible, to hack together a
replacement from component parts. I was wondering if anyone knew of any
SIMILAR adapters. I recall the Colecovison, and the TI-99/4 both had 4
pins. Amiga and VIC20 both have 5. Do their outputs look like this at
all? I have these AC adpaters, but they're 3 hours away right now.

ANyone know a replacement?
