Is this battery only?

Yes, battery (2 9V) only.

I agree, excellent repair work, karter!

These DO also work with the proper AC adapter - in addition to batteries.

Some do. This one doesn't seem to have the jack for the AC adapter.

Steve would add the jack as an upgrade (I think it was for 9v DC wall wart) on early units.
