"I don’t recall power cords being a big issue in the 70s-80s . . . "
We have been thoroughly brainwashed thru marketing close to 50 years now.
My posts didn’t mention the tuner is connected to a PS Audio Powerplant which is plugged into wiring/panel that’s been updated. Perhaps the "clean power" negates any PC upgrade?
Having a captive PC, I’ll never know🤣
MD 108/108T is still a top notch FM tuner with/without aftermarket PC/IC’s.
I have vintage Amperex Bugle Boy tubes in the audio out and that seems to make the only noticeable difference.
Again, YMMV.
Since we’re talkin FM tuna’s we all know nothing will make up for inferior antennae/positioning AND quality broadcast (which is in short supply, unfortunately)
LONG LIVE FM RADIO!!
