[pics] 4,700 AXIAL CAP REPLACEMENT

Post by spiny » Sun Oct 22, 2017 9:02 pm

A few more pics from this evening - managed to find some time to do atari stuff :)

This is the cap replacement kit for the big cap that lives on FM and STe boards (though interestingly, not on MEGAs, it's a different shape on those)
Again, dont be put off by the fact it needs soldering, a methodical approach and a half decent iron, and you'll be fine.

used my 'good' camera for these pics, but still need to work out a good way of mounting it on a tripod so I can photo the 'workspace' properly.


Parts:

lining up the new caps, long leg is positive, short is negatibe. negative is also marked on the cap body.

and thats it. note the plasic portion of the jumper pin is underneath - this will space the board away from the ST motherboard to prevent shorts.

Haven't had chance to fit it to my main STe yet, as i'm currently using it, but pics of that stage will be posted when I get round to it :)
