Sony PS-Q7

1 9 8 2 august 1982

Part of the FH-7 system, aka Heli and available in three colors, the PS-Q7 quickly became one of Sony's better remembered component and sold very well on its own, even better than the PS-F9 Flamingo.

The japanese versions of the Q7 had an FM antenna at the back to do away with amplifiers and transmit the LP playback directly to an FM tuner or portable boombox ; said antenna has a red LED glowing at the top when transmitting :)

The original japanese packaging for the PS-Q7 was sadly not exported but really deserved a Good Design award - click the USER button below !
The optional SBMC base for the Q7 which you can see here wasn't exported either and it doesn't even have a name in the catalogs...

Sony also made the PS-Q3 (belt-drive, no 'phone out or RIAA amp) and the PS-Q9 (a Q7 with added Control S plug), both in brownish-black and without the superb packaging.

A thread with detailed descriptions and nudies here.
