> After a few wiring changes, I have between the positive side #26 and plate of 7A8 29.2 ohms. And from positive side of #26 to plate of 7B7 20.3 ohms.
Ok so that's good.
>Watching B+ on power up and looking for around 95V, shut down when voltage climbed above 105V.
105v is not much of a big deal, filter caps are rated @ 150 or 160v. Typically the dc output voltage isn't
going to rise above the ac input to the rectifier if there is some load on the p/s.
>May have done some damage as on 2nd attempt B+ only climbed to around 30V.
Seems like you have short somewhere on the hv rail or a weak 35Z3.

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.
Circa 1966
Now I think I've got!
