Thank you for responding.

I have a B&K Isolation Transformer, and a B&K Model 1077 Television Analyst. I have injected an RF signal at the antenna terminals (nothing). I have input an IF signal at the 3rd IF amp (very faint, fuzzy test pattern outline, no sound). I repeated this at the 2nd and 1st IF amps, with the same results.

I thought maybe the low 435V Boost might be part of the dim raster issue, but I can't seem to correct it.
