Was asked to find out what AC power adapter would work for a Sony Water Resistant 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/US/p/model-...34,37,43,117,5

Did a forum search using Sony AC adapter but only thing found was https://groups.google.com/forum/?fromgroups=#!searchin/sci.electronics.repair/AC$20power$20supplies$20Sony$20portables/sci.electronics.repair/s_Uq6LBcjPY/igbndPsdWCYJ and it was for a portable Sony CD player.

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

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

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:
