Yes these are the units with the bad yoke, but it's usually
R007.  If it overheats & goes out, it can be the yoke doing
it.  Check for voltage drop across R473.

Was dead. Found shorted HOT (2SD1879) Replaced,now narrow
picture,Reg B+
low. Replaced the STR30130,no help. Found open 2 watt R004
(5.6 ohm) in
power supply.Also many cold solder joints soldered.Replaced
R004. Now
screen wide enough, B+ at proper 129VDC, but seems the HOT
may be
running rather hot.I can't remember if this resistor was the
one that
indicated a bad yoke.Thanks.
