Sony STC-7000

Circa
1 9 7 1 c.1971
1 9 7 5 1975

Sony's only "pre-ceiver", very much on the high-end side of things.

One french catalog states that the FM ssection is derived from the ST-5000F and the preamp section from the TA-2000F...
More realitically, the tuner section is equivalent to the ST-5130 bestseller and the preamp section is somewhere between the TA-1150 and TA-1130 bestsellers.

MOS-FET driven 5-gang capacitor with 8 filters, FETs everywhere (FM and AM) and a surface-mounted IC - almost a first in 1970.
Also separate V and H oscilloscope and audioscope outputs.

Low-noise IC in the preamp input, level pots for the Tape 1 and Aux 1 inputs, dual stereo plus center-channel outputs, all good for a tri-amplified system ending in a pair of SS-7600.


Nowadays not often seen because the original pricetag was quite majestic as well : 550$ !
