You are right I errected a metal shield between it and the crt and the noise just about dissapeared so that is that ...now i have a linearity issue with the top being stretched and some weak sync
I swapped the sync clipper the H osc and the V out 6SN7 I think (off the top of my head )
The tubes are all the same swapping them around will give me short vert or short horis or weak sync so at least one is weak... I have some picts ...
The first pix is What it looks like with the metal shield i layed in as you see it in the sec pix
the 3rd pix is the noise
without the shield
the thing i was working on it flipped on its side
so it had not occured to me the noise might be the shield untill late in the day just before I got your post..!!! LOL
The CRT realy looks good any advice on sync? weak coupling caps maybe?
or linearity ?? resistor off value on a plate?
