I see that CCrane Witness USB AC Adapter is on sale for $9.95 right now.
This analog regulated supply (as reviewed on my web page) works very well with other 5 volt mini-USB powered sets for MW/SW RADIO use (not just for charging) as it’s NOT a switching type supply or contains any switching type regulator, so no switching supply RF noise.
See the bottom of either one of these 2 web pages for my comments (if you have not already).
Many thanks for the tip, Dave! At this price, I think I may pull the trigger.
