k7400 help

Ya it is repetitive clicking, where is the hot? I'm new to these lol. Also I was reading and some people say it could be the b+ adj. And what is hv shutdown I see the b+ pot and the shutdown pot both friggin glued up.Flyback and everything looks good I don't see any cold solder joints or anything blown up.
 
hOW HANDY ARE YOU WITH ELECTRONICS REPAIR IN GENERAL? What do you have for soldering and desoldering equipment? Lmk. It will make a big difference in my answer.
 
The HOT may be your only issue, as it can blow for various reasons. It is located on the big metal wall to the right of the flyback, closest to the edge of the board...
 
Black lead on center leg, red lead on each of the outer legs. Use diode test. Beeps or zero is bad...
