Think about replacing the beasts with tantalum equivalents. Essentially all of the aluminum jobs are nothing but bypass capacitors on the +5 or +12 volt power lines. The capacitance is never critical and can surely be replaced with a tantalum job rated higher C. Somewhat smaller is also probably OK because of the superior AC resistance specification for the Ta parts. The voltage rating is important. At least 50% over the DC voltage is nice. But watch out for Apple. On the SE/30 they use 16 volt caps for everything even though they could have used 6 volt caps on the 5 volt rail. I have some aluminum electrolytics here that work fine after storage since the 1960s. It's those smaller and smaller "modern" devices that have the problems. -- --> A fair tax is one that you pay but I don't <-- -- ----- You received this message because you are a member of the Vintage Macs group.
