Unknown Ballast

Anyone know who made this ballast and what it runs? Is there an easy way to figure this out? Only markings are W-7-53 and a bit of paper label and appears like an 8' Slimline ballast but is taller than the normal Slimline ballast more like a HO ballast height. Was in a box lot of ballast that mostly contained slimline sign ballasts though.

Those are actually HO fixtures that I bought as "working" at least they look nice. Output from the ballast was 0.5 - 0.6 amps while input was about .9 A. All 25 had R-2S110-TP Advance ballasts with bad caps. I opened the end of the ballasts and replaced the caps now all put out the proper 0.8 A. Curious to see how long they last now. Caps came from a surplus store and are rated 4 uF @ 600VAC.

My best guess is a 2x96T12 Slimline ballast.

I like my lamps thick, my ballasts heavy, and my fixtures tough.

Looks like it, judging by what little is left of the wiring diagram and how many wires exit the case. Also, if I had to guess, I'd say it's a GE.

I was thinking GE too by that little bit of sticker...

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

That's a GE.

The more you hate the LED movement, the stronger it becomes.

That looks like a GE. Are those wires cloth? Judging by your description and the older looking remains of a label, you may be looking at an early slimline ballast! Have you tested it?

Yes the wire covering is/was cloth. I did test it with some 4' and 8' T12 slimline tubes and it does still work around 440 mA output wired like an advance SM-2E75. Next question though is this a lead/lag ballast similar to Advance S-275-S or a series ballast similar to Advance SM-2E75?

Use it to light up some lamps and point a cell phone camera at them. If it's lead-lag, the lines on the camera will be offset between the two lamps.
