This baseline ES-tuner is very easy bettered in
soundreproduction by a swap of the RC4558P and
four coupling caps in the analog output stage.
Put in a DIP8-socket and,say, a OPA2604,and this
little piece is not only ultracomfortable but very nice
sounding. Certainly on eyes-hight with way more ex-
pensive and massiv build vintage gear.
This tuner is a good example how back in the day
technological progress actually translated to a better
product for the enduser and not only cheaper
