I owned several of them throughout my years. Should have kept at least one. What amazed me most about the design ( everything actually ), a single power transformer was used ( obviously a price decision ), and it still sounded spectacular !
I bought a 3020A more than 20 years ago to drive external speakers with my TV. With the right speakers (many options I'm sure) it can still offer surprisingly musical performance. Mine is stock other than replacing the speaker spring clips with miniature 5-way binding posts.
I had two of them back in ’78 - ’79. Cost $219 each. Used them as mono amps (one channel per speaker) with a pair of Time Windows. Sold them (and the TW’s) when I bought Quads and a Bedini 25/25 (and a little later, a Futterman OTL). But the two 3020’s driving the TW’s single-channel sure sounded good!
