Top 5 recievers of the 70's and 80's ????

Nakamichi: SR3a

👍 although I prefer silver faceplates

Radio Shack’s Realistic STA-2100 should also be a serious contender

Fun topic for sure 👍

I’m more of an Integrated collector but do enjoy a Marantz 2330 (restored by Many Moons Audio) that should qualify. 
Beautiful looking single year (1st gen - 1979) production that, I believe, all featured engraved faceplates. Looks particularly snazzy wearing it’s Pathe Wings walnut WC43 cabinet.

Others to consider would be Sansui G8000, Pioneer SX1250, Concept 16.5 & Kyocera R861. The Pioneer because it’s all discrete and AFAIK the only receiver that doubled down power into a 4 ohm load.

Honorable mentions to TwinPower HK units, Sherwood & Sony
