Sansui recievers are almost always available on ebay but the usual warnings apply. Sansui produced a lot more integrateds and tuner combos or so it seems. You can get an excellent AU717 amp for less than $300. If you aren't to fussy they made some later digital tuners the T-60 and T-80 that sell for a lot lot less than the TU series of analog Tuners typically only about $40-60.
The best of the black face 70s vintage gear might be Nakamichi although the 600 series was slant shaped. An underappreciated company from that era IMO was Nikko which came in silver or black. You should keep in my mind the the black face also heralded the end of that particular quality era when Japanese manufacturers started to outsource to the rest of the Pacific rim. Thus, for instance, Pioneer collectors seek mainly the Silver period pieces.
BTW One big name that was almost always black is McIntosh but good examples one of their few recievers go for insanely big money. The only exception might be a 1500. Recently I have seen "mint"/excellent examples of the 4100 go for over $1200.
