Are you sure it's a cold? The COVID tests these days test for all sorts of stuff. So far my health issues have been allergies, but I do wear masks indoors in public places.

If you find yourself needing another receiver I can let you know about the state of the ones I have here. I'm using one that came from Goodwill, a JVC RX-5022V (this sale has pretty good images) I got for under $20 and an OEM remote control was inexpensive. It took me a while to get the various speakers set up (I use two excellent ones from my dad and some good smaller ones from Goodwill). I have a handful of small speakers also, good brands. Some of the receivers are pretty heavy.

British murder mysteries on PBS tonight to go along with a jigsaw puzzle; they don't take themselves so seriously as some of the gritty American series (the various flavors of Law & Order and CSI, etc.)
