Who’s been tinkering while trapped?


Have you been using any of your forced isolation time over the last few months to tinker with your HiFi gear between Zoom meetings and reruns on TV?  If so, what have you done, what have you learned, what’s worked and what hasn’t worked?

Yes I have been tinkering, but really only a little bit more than normal. Being retired and a homebody by nature it's been business as usual as far as dealing with my system and music collection. Enjoy the music
There’s always something. Latest brainstorm ⛈ ⛈ Mystery Tweak for Cassettes following close on the heels 👠 👠 of Mystery tweak for CDs. I’d really like to say what the Mystery Tweak is other than a stiffening mechanism but then it wouldn’t be a mystery any more, would it?
