Is there an idiot's guide to replacing capacitors somewhere? About the
only tools I have for this are a workbench and one of those cheap
Weller soldering irons.
I second that!
Some interesting hints are to be found here , but were written for the SE30.
For instance, there is no mention of the transformer-like part with its
"Danger - High Voltage" label, which sits on the upper section of the sweep
board, and connects to the middle of the left hand bevel side of the CRT by
means of a rather thick brown cable and some kind of plug(?). To remove the
sweepboard, this plug(?) obviously needs to be disconnected from the CRT.
Can someone tell me how this is done? Simply by pulling or twisting it off?
And how many days does a Classic need to be disconnected from the mains (=
plug out of the socket), before all hazardous residual high voltage has
disappeared?
On the analog board I counted 7 "chip type" caps, marked 'W4 47 16V', and a
smaller one marked 'DOR 1 50V' (did I miss any...?). Is there some kind of
code to translate that into microfarad? According to the above mentioned
page on the SE30, chip type caps are hard to find, and could be replaced by
radial type caps. Hence the need to know exactly what rating is needed (I
guess...).
A final question on the sweep board: due to my problem with the lead to the
CRT, I've not been able to remove it yet, but it looks like it has over a
dozen "can type" capacitors of varying sizes... Do all these need to be
replaced as well? Just to remind you, the problem with this Classic is the
sound and date/time which do not work anymore.
Thanks for bearing with me, and for any additional information on how to
proceed (I checked out MacFaq.org and Gamba's place, but didn't find the
answers there).
