This is a difficult set to obtain voltage readings from while assembled, based on your description of observation. Assuming both H and V are off-freq, Are you able to feed a signal in and see multiples of a "rolled up" picture?

Never, ever underestimate how "far off" a post-war set can get on both sweep frequencies.

In the meantime, one thing you need to do is get a tube socket extender for both octal and loctal tubes so you can scope and meter those tubes in operation. I have neither of those extenda's myself. But I do have a CRT available if you bring the chassis and yoke/focus coil with you.

That way, we can sub in some vertical drive from a Sencore VA48 or a B&K model 1077B analyst to the 6K6 grid and clear your output stage. sometimes you need "modern" equipment to nail down trouble in early sets.
