Looks like it will come out nice !
1) the minor width problem may be the HV control has a
bad spot, common, used to stock it. Just turn it a little & it will pop in.
2) we did change a lot of filter cans on these. It can be changed
without a chassis pull but you have to be very careful.
3) degauss thermistor 63-10710 IIRC prob fell apart.
4) turn off chromatic switch & turn color all the way down.
if you still have color bars / blotches you need to
do purity & crt set-up.
5) lack of snow most likely IF transistor but could be something else.
Let us know how it goes.
