Well, I just didn't want to add a cassette deck on top of my KR-4070 receiver, as it's kind of overkill for my bedroom. I didn't want a big stack of components on top of my dresser. And I have other uses for the KR-4070 (driving a pair of ratty-but-awesome Cerwin Vega VS-120s in my garage, for instance).
Finding this little receiver on eBay for $15 bucks buy it now was pretty awesome. It's in great cosmetic shape, and just needed a bunch of small issues fixed. (bad trace, corroded solder joints, broken azimuth adjustment boss, blown bulbs, and lots of deoxit in the selector and record/play switches)... and it exactly suited my needs. It also looks pretty slick with that gold/bronze finish.
I dunno why anyone would make fun of me for wanting a receiver that exactly suits my needs... I want to play tapes and not have the system be overkill for the space. I have a huge collection of cassettes and am constantly recording new ones with TOTL (for their time) decks. (Pioneer CT-F950 does most of the recording, but I also have a CT-F900 and a Nakamichi BX-150 in use)
For specs, it's 12wpc, very suitable for a bedroom and bathroom. It's driving a pair of Paradigm Mini Mark 3's in the bedroom and Minimus-7's in the bathroom. It cost $370 new in 1979, which is $1200 in 2015 dollars. Not exactly hi-fi, but it wasn't a total POS either.
