You can find any Mac tuner at Audio classics. The mr78 is legendary. The downer is fm signals are not from analog sources any more. And converting to digital?..ugh. If you want digital, a magnum dynalab Sirius XM is a very good choice. There is a plan to purchase both a terrestrial feed and a car feed in one plan. I always enjoyed listening to cousin Bruce Morrow and the 60s music. I’ve owned a tandberg 3011, and that was very enjoyable too.
good luck.
