thats easy, so a soft start, no recapping needed most likely.
I do this
pull horz out and vert out tubes
monitor the B+ (look for a 400v b+ on the chroma board, easy to get at)
monitor the AC input voltage and current.
variac to 10vac to the plug, watch the DC voltage, should be about 3-4 times as high as the AC at the plug, also note the current should be nill.
after about 10 min go to about 30vac this time feeling the can caps for heat and seeing if the DC keeps going up and the current should still be low.
get to about 90vac if all looking good with low current and high B+ the pop the HO and VO back in, hook up a current meter to the HO cathode lead, hook up a HV prob and go for a full power start.
pull the plug if the HO current starts to go north of about 220ma, there is something wrong if its there and no HV.
if all goes well dip the eff coil with the HO meter still attached and call it done.
keep an eye on it of course and see how it goes, check the heat of the fly after about 15min of running (power off of course).
the most likey issue will be vert stability. those caps in the feed back loop of the vert multiplier live a harsh life.
