Zenith F1150P1 Troubleshooting

[ThePlague]

Hello all,

I recently acquired this B/W TV out of an old motel. Its missing the original power plug so I had to use the standard two pin cable on the wider prongs for AC. Seems to work okay, but with a host of issues.

I get a lot of retrace lines and get a triple, double, sometimes quadruple image depending on the horizontal sync setting. I believe there is an issue with the oscillator, but I am having issues finding any kind of information on this unit.
The screen is also shrunk horizontally. I figured there would be a horizontal size pot on the inside, but no such luck.

I was wondering if anyone has a service manual or any advice on how to approach this TV. Any information or where to find it would be much appreciated.
