OK....
found out a few things...
the 8yp4 does NOT work with thing
I had to go grab the 21aup4a from the Stromberg.
using a signal generator, I was SORT of able to recreate Vert osc, but It is not perfect.

It will have to do till I get the transformer from ETF.
HORZ looks fine, IF is obviously messed up, but working mostly.
and it DOES look like this thing will work!
