The model above, the rather rare STR-7065, added a little power, a slightly better MM phono section (+2dB in s/n ratio) and, mostly, a supplementary meter for FM input signal strength and, even more mostly, additional LEDs set witgin the scale window that show which source is selected. The rest is identical : 4-gang varicap, a nice fat power trafo, large heatsinks protruding through the back, two pairs of Sony PNP / NPN power transistors, three pairs of loudspeakers' outputs, a separable pre/main loop. Lots of inputs, outputs and lots of hectic cabling, too.
At 3295FF (french francs) in 1973, this was the high-fidelity of the fairly rich and this still shows today - in spades.
