Jay Allen wrote a review of the S-2000 and I'm not too sure whether he liked it or not! The multiple peaks as he tuned through an AM station sound like the DSP is phase locking at 2kHz steps and he doesn't give top marks for the audio quality which I thought was supposed to be the main point of DSP. I'll stick with my Sony CRF 5090 as a table radio!
Incidentally the Sony has a 'nose' on the power plug which contacts a microswitch as you plug it in which disconnects the batteries - the dial scale lights are always on when you are running on external power. That produced a problem for the previous owner - the dial scale warped with the heat from the lamps - I changed the lamps for LED's while sorting the scale problem. I would imagine if the battery icon on your S-2000 shows full when running on power with no batteries installed then that's your indication. It would be nice if there was some positive indication - it's easy enough to plug in the power cord in but forget to flip the switch then find that the batteries are flat!
Your Sony would be an oldie but goody.
Not sure on it's age, be but I used to work for a guy 45 years ago, who brought one very similar back from Aus.
Still getting familiar with the S2000. I find it like a big brother to the 660.
I love the big tuner, lot easier for me to use.
I have Neuropathy in my hands.
I read all the reviews I could find before I bought it so had a fare idea what to expect.
What I wasen't expecting was the big power plug on the cable.
Won't fit into the pocket at the back.
I bought it direct from the Tecsun dealer in Sydney & I am assuming they would have fitted that to match our mains, as it is a screwed type.
I have emailed them regarding that.
