Took it apart tonight to have a look around and found a bad fuse, not blown just failed open from old age.
I didn't have an exact replacement and I didn't want to just put a jumper on it but I found a small pigtail fuse and managed to wedge the tails under the ends of the fuse holder well enough for a test run.

The set fired right up with sound but no light appeared on the screen, I fiddled around a bit and when I moved the antenna connector block around (it hangs loose with the cabinet removed) it suddenly popped on, I guess it was shorting on a heat sink nearby.
Fired up the B_T modulator and was able to tune in a picture though it was a little out of focus. I lucked out and had an adapter for the CRT in my B&K and tested the tube, it's pretty tired, high end of the bad scale but I suspect that's why the focus isn't so great even though it has good brightness.

Other than that I just cleaned up the parts of the cabinet I had removed, and the knobs, the owner was a smoker and it was covered in heavy brown crud inside.
I still need to remove the chassis from the bottom of the cabinet so I can clean that properly.
The grille cloth comes out and I washed and bleached it back to white, it was really nasty brown from the cig goo.

Here's a few pics of the innards, the HV and sweep chassis is located inside the top cone part behind the CRT, the radio/TV chassis is in the bottom.
