It's possible some of the stations were available through a window or two.
It's also probably worth an alignment.
If you have a local station that does live acoustic music concerts you'll have a high-end analogue source.
You lucky bastard!

Hi Tim,
The front of the store is glass, but this is a very big, warehouse style store. I have tried many tuners in this type of environment. Most can't get anything, let alone stereo.
I wasn't aware that you needed to align digital tuners. I thought they stayed pretty much in spec.
I have 3 good stations. All of them are National Public Radio. I do feel lucky!
I will be installing a small yagi in my attic. A tuner this good deserves a good antenna!

It may not of course, but worth checking.
And the caps, and the output stage.

What would be the symptoms of an MPX decoder out of alignment?
A recap wouldn't hurt!

IME a good way to tell is on an acoustic live broadcast miked in simple stereo, and if your T80 gives more hall sound then the new one needs adjusting. See * as well.There's probably a separation adjustment.
Better caps will sound better, if it's getting close to 20yrs old the electros may need replacement. Bypassing the last new/still good electro PSU cap, at least, won't hurt. IME the higher the PSU storage, without stressing the PT, the better the sound. If the rails are regulated check that chip's operation, too.
The audio output stage, even if it uses a stereo chip, is worth tweaking, because the sound stands and falls there. Depends on the chip if to upgrade it. NB circuits can get a lot more out of 'underrated by 'philes chips'. Running it a bit warmer - more Class A - for example.
One definite benefit here can be getting good deep bass, given Neff's point about light bass. IF there's a 50Hz? (or lower) high-pass filter - wherever it is - ditch it. And, use a bigger (more uf) good-sounding coupling cap than is in there, in any case. * Deep bass is a factor in hall-sound.
IME of very good FM sound quality the bass can be a lot deeper than 50Hz.
My overall point is that you got the thing for so little and its potential is quite high. :-)!
How is it sounding already?

Hi Tim,
Thanks for the advice!
It sound very good but I have only played around with it. I plan to seriously listen this weekend, when I have some time. I will also compare it in depth with the Yamaha on some good stations. Then I will get the top off. You never know when you buy equipment in thrift stores. Sometimes it is already modified, but usually it is better if it is not. There are a lot of hacks out there!
