Hey all, just picked up a vintage Harmon Kardon HK-730 receiver and although it is a dual mono design, I was curious if it was possibly a common ground amp. Much like the first series of Aragon 4004, 2004 amps. I picked it up to see how it would match with my RTA 12Cs. Thought about hooking it up to the CRS' (pin/blade) to have a listen as well but don't want to blow anything up. Have read nothing but good about the quality of sound and bass extension from "just" 40 WPC.
And WOW, this thing is a heavy mother.
