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

Marantz 2270, I wholeheartedly agree!
Tandberg TR2075 and 2080 are up there as well.

Marantz 2285B
Yamaha CR-3020
Pioneer SX-1250
Concept 16.5

Hands down the Luxman 1120A. Sorry, but I've either owned or listened to much of what is talked about in the previous posts and for musicality, power, tuner section, phono section, it's Luxman. Still easily valid today against most equipment.

Sony STR-5800SD

Good grief, no mention of Yamaha?

They were inexpensive, ultra reliable and had vanishing low distortion specs combined with great sound and forward looking cosmetics.

I personally sold thousands of dollars worth of them with a very clear conscience. Their small model had 5 year unlimited warranty, a great tuner, variable loudness compensation, a fine phono stage and real wood cabinet for $199.00.
