I think I know the answer to this ("no") but figured I'd check just in case. I have an old Sony Walkman which accepts a 3V AC adapter. I don't have such an adapter, but I do have a 4.5V adapter (from a Sony Discman which, oddly, runs off of only 2 AA batteries otherwise).
So you can guess where this is going... can I use the 4.5V adapter with the Walkman or will this cause bad things?
Thanks for the insight, Mark
You should get the proper adabtor. The tollerance for these walkmans is not very much. your Walkman could probably take about 3.5 V at the most.
When connecting power up to your Walkman, take care for the polarity, and the voltage. This is very important, if you don't want to damage the Walkman.

Before taking my suggestion - read the other posts!, but I have a couple of cheap brand personal tape players which both use 2x AAcells and both have "4.5V" marked next to the external power jack.
Fizzzt. Bang!

3 volts AC adapter? AC? That, when rectified and filtered gives you 4.24 volts of DC.
If you have a 4.5 VAC adapter that you want to use, you can add a few diodes to drop voltage. A silicon diode drops point six volts when forward biased. Two diodes (or three may work better) will drop 1.2 volts you'll just be point 3 volts too high . . .
It will take a pair of diodes for AC so a total of 4 connected back to back so each diode is forward biased on one polarity of the sine wave.

Maybe if I were running off of a breadboard and not an integrated device with a tiny power port, I could consider this :)
Anyway, thanks everyone for the advice. I picked up a switchable adapter for about $9 and am using the recommended 3V setting.
