I recapped a IIx board a very, long, while back and thought I would fire it up tonight. So, I hooked up a monitor and keyboard, pressed the power button and ... nothing.
I opened it up, checked the batteries that I had put in it when it was recapped (probably over a year [or two?!?] ago) and both were practically dead. Since it had one of TT's battery boards in it, I put in some nice, newish, fully charged batteries and I tried the start button again and ... nothing.
Since it had been a while, I looked up how to 'jump start' a Mac II and when I performed that procedure, the Mac booted right up. While taking a look at things, it looked like C3 was not installed, so I checked the internet to either find pics of the cap that listed its value or the value itself. I can't believe that I did not install one, when I recapped the board, but it is just a set of clean holes where the axial capacitor C3 should be AND I cannot find the values (I would like both uF and voltage).
If anyone either knows what it is, or can check their Mac IIx board and pass along the values, I would appreciate it.
I did find copies of the II/IIx startup circuit that list it as 47uF, but I would appreciate an answer that is based on what was physically installed or successfully used as a replacement.
