So what we are doing is disconnecting the hv to various stages to try and find where this noise is coming from. Seems like the osc is ok so it's on to the mixer (resistor 30) if that makes the noise go away there's a good chance the mica cap in the ift is bad but we'll see.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
