Crazy HV issue on a Tele-Tone TV149

[Kamakiri]

Almost done with this chassis, which will be for my replica pre-war set from this thread:

I'll start by saying that I've replaced all of the usual caps, the 6KV deflection caps, and all of the caps underneath the HV section. Replaced the 60 ohm Candohm also, along with most of the resistors in the HV section. A few had drifted north, but not by any shocking amount.

So here's the screwy part.....

Powering it up, at about 75 volts, I get a picture and sound. Huh??

The picture is small, as shown in the pic, and doesn't get any larger with more voltage. Lousy pic, but what picture *is* there is perfect. Sound is perfectly clear, picture locks in great, etc. Width and height are at max. I can center the picture easily as well.

I don't have a HV probe, I just use a neon bulb. According to the brightness of the bulb which I've used for years and am accustomed to, this set is putting out a crazy amount of HV for an electrostatic set. The HV adjust is turned fully clockwise, and turning it counterclockwise only increases the brightness of the picture and shrinks it.

I've checked every resistor I can think of in the circuit. I swapped 12SN7s around just for grins. Here's a link to the schematic....usually I'm pretty good at figuring things out, but this time I'll admit that I don't understand how this circuit works or what the suspect components could be.

I haven't tested any voltages at this point because I don't want to run it for longer than about half a minute and not at full voltage. I don't want to risk overloading anything.

Ideas as to how to proceed? Thanks!
