Onkyo A-7

Healthy and powerful 1970s.

The A-7 is powered by a 4,8kg power transformer and 2x 25,000µF caps.
The driver stages are a p-p Class A design while output is Class B.

Low-resistance copper grounding tracks to limit the influence of dynamic transmodulation, keep internal impedance low and stereo separation high.

The phono section is a low-noise differential input with Class A p-p, allowing linearity and high input level - 230mV at 1Khz.
And all the usual functions : bass & treble controls with two turnover frequencies each, subsonic & high filters, tape dubbing both ways, stepped attenuator and tone controls etc.
No DC circuit, though, and no deported input/speaker selectors - lots of wiring.
So the A-7 is simple, healthy, powerful and will last forever.

Designed to be housed in a bigga wood enclosure (therefore much better looking) but said enclosure is... Invisibilia ; It seems the bigger A-10 was export-only.
