Was asked to find out what AC power adapter would work for a Sony Water Res
istant Sports AM/FM Cassette Recorder Model CFS 902.

Did a search of Sony's website but only found the primary user manual which
 was not give a rating for the AC power adapter. http://esupport.sony.com/U

Did a forum search using Sony AC adapter but only thing found was https://g

ndPsdWCYJ and it was for a portable Sony CD player.

Realize the important thing is to get a AC adapter with the correct polarit
y (+ outer).  

Am interested in any suggestions in choosing an AC adapter for this Sony po
rtable.

FYI: Every thing works OK on batteries.

The part number is: 1-463-968-11  Model is AC-940
It looks like a 9V adapter and uis no longer available from Sony.

I may have one at the shop.  Where are you located?

The manual you referenced gives enough information to figure it out.
The CFS 902 uses 6 'C' cells.  That's 9 volts.  It will operate for 27
hours on alkaline batteries.  Alkaline 'C' cells are rated at 8000
mAH.  Doing the math, that's 300 mA for 27 hours.  Add at least 50%
for safety.

So you are looking for an AC adapter rated for 9V, 500 mAH with the
proper connector.

9 V / 500 mA seems okay:
