002- Are the power supplies for the ][+ and IIe
interchangeable?
Yes. The plugs are the same and the ratings are the same and they look
alike. Aside from, possibly, needing to add mounting holes for particular
models, you should be able to swap ][+ and IIe power supplies whenever you wish.

003- Could someone compare the output capabilities of the
GS and IIe power supplies?
Okay. This is from information presented in GS and IIe manuals:

Pin# (GS/IIe) Volts (GS/IIe)
7/6 - 5 V 0.25 Amps /0.25 Amps
6/5 -12 V 0.25 Amps /0.25 Amps
5/4 +12 V 1.00 Amps /1.50 Amps
4/3 + 5 V 4.00 Amps /2.50 Amps

1/1 GND

004- Can I use a 'generic' surplus power supply in my
Apple II?
Sure. Check out the power supplies listed in the MPJA, JDR, Jameco, and
similar catalogs (see http://home.swbell.net/rubywand/A2FAQs3VENDORS.html for
links). Mainly, you are looking for a relatively compact switching power supply
which fits the following guidelines:
1- all four Voltages (+/- 5V and +/- 12V) are available*
2- the power supply can be fitted into your Apple II
3- the +5 Volt output is rated at 5-10 Amps
4- the +12 Volt output is rated at 1.5-3 Amps
5- price is no more than $25
