RE: Charger Specs for Rockwell 74k Calculator
Update to the update: Likely the key difference is yours is for UK (240V/50Hz) and the one I found is for US (120V/60Hz).

Thanks for the info Zaphod. I'm not certain if the 74k originally came with that one, but another member that has a 74k came with a different one:

Model: DC-410P
Output: 4.5 VDC 100mA
Tip: Positive

This is more of a traditional small black 'wall wart' design. I was able to easily locate one and will post a family photo once I receive the adapter.

Thx again.
