I need to recap my Apple II Plus power supply, model number 605-5703 / ASTEC # AA11040/B. I purchased the appropriate recapping kit from:
When I began the process of recapping the power supply the first thing I did was to take pictures for orientation (to note the positive and negative leads along with notating whether the marking on the capacitor was for the positive or negative lead) and the corresponding capacitance and voltage values. I then compared this list with the parts from the kit and noted the following two discrepancies:
and they match. I also doublechecked the power supply part numbers (both Apples 605-5703 part number along with the ASTEC #AA11040/B) to ensure I purchased the correct kit for this model power supply. All looks to be in order and matching except for the three capacitors installed in the power supply. I don't believe anyone has recapped the power supply before as I had to drill out the two rivets on the side and the PCB doesn't show signs of any hand soldering.
Does anyone have any familiarity with different model ASTEC power supplies which might explain this? What issues might arise if I were to just use the kit capacitors instead of the values of the installed capacitors? My primary concern would be C12 which varies not only in power rating (10 versus 16 volts) but also capacitance value (1000uf versus 680uf). I should note that I've used this exact kit to recap other 605-5703 power supplies and the parts matched exactly, this is the only one I've seen which varies.
Thoughts?

I then compared this list with the parts from the kit and noted the following two discrepancies:
- Two of the 1000uf capacitors, C13 and C14, are 12 volts instead of 10 volts (the kit contains four 1000uf, 10-volt capacitors).
- One capacitor, C12, is 680uf / 16 volts whereas the kit specifies C12 should be 1000uf, 10 volts.
