Atari Power Brick/Transformer Assembly--Help Identifying?

I have an old used Atari Transformer Assembly/Power Brick/Power Block I just picked up a couple of weeks ago.

I've used the RealBobRoberts Atari Power Block repair kit and replaced the bridge rectifier, the fuse bank, Big Blue, and the wire connectors.

However, it seems like it's different than my Star Wars power brick. And Bob's kit of Atari fuses doesn't match up at all with this Power Brick.

For one, there are only three purple wires to connect to BigBlue(tm) and the fuse bank has the following requirements:

F1: (Main Fuse) 10A 125V Normal Blow

F2: 4A 250V Slow-Blow

F3: 2A 250V Slow-Blow

F4: 2A 250V Slow-Blow

F5: 2A 250V Slow-Blow

F6: 4A 250V Slow-Blow​

Also there is no connector at J4B. I imagine this could be just because it's used but I was wondering if this PS was used specifically for another game like Tempest or something. Maybe Tempest or another Atari game doesn't need that connector? I'm going to pull my tempest out from the wall in a bit and check myself but I thought I would ask around for the differences in power supplies made by Atari.

Is there an FAQ that someone has out there to help identify which PS goes with what? I realize that's probably not the case since most people would know what they have in their machines just by looking.

P.S. Are all bridge rectifiers manufactured the same with the + and - at opposite corners?

Thanks for any help.

Unfortunately, the number of my transformer is not listed in the link that was posted.

I feel kind of like a fool for buying this as I had planned to use it with my Star Wars test harness but it clearly isn't a Star Wars Power Block.

The numbers on my Transformer are printed in white ink as follows:

A042082-01A
37-8421

It's restored fully now but I have no idea what it's for. Whoever had used this before had also used the wrong fuse at F1. It calls for a 125V 10A and the fuse that was in it was a 32V 10A. I know you can use a fuse with a higher voltage but not lower for sure.

As soon as I find out what power supply it is I'm going to unload it in the Trading Post.

That's about that AR boards... the OP is talking about his transformer assembly (aka power block or power brick).

Heh. A042082 is the P/N for a TX-1 transformer. Good luck finding someone that needs one...

If I'm bored later, I'll compare it's schematic to the the one for SW. There's generally a lot of interchangability among Atari power blocks.
 
P.S. Are all bridge rectifiers manufactured the same with the + and - at opposite corners?

AFAIK, yes, all "square" bridge rectifiers have + & - at opposite corners, and the + corner is indicated by either a cut corner, or a turned lug (or an actual + mark).
 
I had planned to use it with my Star Wars test harness but it clearly isn't a Star Wars Power Block.

Comparing the schamtics, there's no way that TX-1 brick can be used for SW (or probably any vector... or likely anything other than TX-1). It lacks the 36VAC center-tapped, and the 50VAC CT. Instead it has 3 120VAC (isolation) outputs, for TX-1's 3 monitors.

Post up a picture and I will try to help you convert it, if you're interested

I successfully have done this myself a few weeks ago, as long as the 1 x 50V centre tap winding is there it can be done

Just need a clear pic of the 15 pin plug pls

Dez... here's shot of the schematic for the TX-1 transformer. It doesn't look to me like there's ANY center-tap windings. Secondaries are just for the rectifier (which generates the 11VDC), the 6.3VAC, and 3 x 120VAC. If you know how to convert that guy, I'd be interested in learning too...
