Early hk cassette decks

[mhardy6647]

Does anyone here know whether there are real (electronic or performance0 differences between the very early harman-kardon hk1000 top-load cassette deck and the later hk2000 top-load deck? The cosmetics were modernized on the latter, but the layout and overall Gestalt of the hk2000 and hk1000 are awfully similar.

Just curious...

The HK 1000 was the first cassette deck with integrated Dolby B noise reduction to be mass-marketed in the USA, coming in mid-1973. (It was not the first deck with Dolby, just the first marketed). It was a very fine deck for its day and one of the early signs that the cassette could be a legitimate hi-fi device.

The 2000 is somewhat similar but had significant differences in internal circuitry and some mechanical differences.
