What is causing the =20, =3D and = signs after each sentence in some of
the emails that I am getting?  Makes it hard to read.

I pulled the 1674 board and changed the 82k and 110k, tho good.
Further=20
tracing located an open 1 ohm resistor next to fly: R3252, which feeds a
=

diode CR3215 that's shorted. My PARTIAL diagram shows this diode=20
produces the +26 volts.
It goes like this:
Flyback pin 4, toR3252, to CR3215, the +26V.
Is this to the vertical Vcc? if so, probable bad vert IC as well.
