Radio blew up. Had to jump in and fix.
Residual problem remains, the audio from the speaker output is slightly fuzzy/distorted, most noticeable with voice. Output from line out is clean. I’m hoping it is just that it is being underpowered. I’ve got a couple of AC adapters on the way from China but that will be a month before they get here.
Received new eBay China replacement wall wort. 2 amp. shipped. Solved fuzzy audio problem mentioned above.
