pretty sure its a powr tranny, I did one a while back, I will see if I can find the link.
I liked working on mine, the chassis comes out easy. becareful of the speaker leads, mine were frozen to the transformer, you do not want to yank on it or you will tear out the female bullet connectors on the audio out transformer.
I just cut the speaker lead and put on some new connectors.
I have been told the anoode lead just plugs into the HV socket. I did not know this and ended up disconnecting the anode at the CRT. That was a mistake since I could not put it back on with out removing the plastic head shell from the CRT, adding quite a bit of work to the process.
If your lucky the fly will be ok. I would not mess with it at all no matter how it looks. just get everything else checked out and see how it goes.
On mine only 1 of the 3 can caps needed work the other (a doubler and 4 section) were ok and are working fine. The bad one was a skinny can multisection that sits right up by the power transformer.
there are several paper caps on board. You need to decide it you want to pull the main board or not. I was able to replace all but 1 or 2 without doing that, the 1 or two were done from the top (crush or cut out old, J hook in new).
I had a couple bad tube sockets and one bad ground stake.
IMHO I would not pull the board unless I knew I had to, but of course this is just an opinion.
you may find a few out of spec resisotors, I had one on the brightness control and a sync tube (think it was a screen, not sure).
lastly the pots that control the vert lin/hight were a bit crunchy.
I spent a good deal of time with cleaner and cotton swaps sticks cleaning the board up so I could see what was going on.
The IF was fine, did not touch it.
