[pics] 4,700 AXIAL CAP REPLACEMENT

Post by spiny »

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:

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.
