I've just found the old apple ][ that has been stored away for a long time (30 years) at my parents place. I want to do a full refurb on it and am currently in the investigation and cleaning phase. It was in pretty poor condition but am working through the process now. So much great information in this forum and elsewhere on the net.
I don't want to fire up the power supply until I see if it needs the filter cap replacement and also until after i have my electrician mate cast his eye over it. I've messed about with low volt electronics for years, but I like to leave mains voltage stuff to the professionals.
So I removed the power supply, which has had what appears to be a minor oil spill on the outside which I will be cleaning up first. Inspecting it showed the rivets had been drilled out prior by someone else sometime in the past.
So I cant see any of the rectangular caps that folks have said are a problem, so this must be a slightly different version to those. None of the electolytics appear to be bulging and inside looks pretty clean. I don't know if the last person to open this has done anything untoward but I dont think so.
So my question is am I right in assuming their shouldnt be anything in there that needs replacing at this point?
Just go ahead get my sparky mate to confirm its safe then check the voltages on the connector and see what happens on powerup?
Thanks in advance for any observations and advice.
