So.....

This is turning out to be a bit more of a project.
I mostly put the whole process on AK forum as I had questions about belts, lubes etc so it could be seen there, but since today I delved into some hardware I will copy some here.

So....tried to remedy another thing.
As I said, the seller refunded me some dough due to a couple of undeclared defects. One of the runs deeper than just the dent in the back.
I looked at the power suply, and here is what the displacement of the heatsink resulted in.
   
   

As could be seen, heatsink is touching the pins of an LDO. What saved it was it is anodized and so nonconductive.
The screw moved and rammed into the board making the hole oval.
I moved the heatsink back, realigned it and screwed to the board.
Then I took two pieces of wood, vice and straightened the backplate.

   

So, as long as I am at it...
I noticed the two larger electrolytics (6,600 uF 35V) seem to have fresh solder under them.
I wonder if they were at some point replaced.
The caps are ELNA, same as many others that are factory installed, so perhaps it was done in an authorised repair facility, though the reason escapes me so far. Also not possible to establish the tine of the repair. The aluminum cans are not going to have datecode on them.
   
   


Tomorrow I will probably start compiling electrolytics list to order.
Methinks with Mouser it will set me back about $100.
Not sure I need to replace all, but that one 3,300uF cap I showed before bothers me, I do not know if it leaked or is glued.
