'82 was about the end of hollow state receivers and amps for home audiophiles. I wish I had dime for every time I heard guys in the tube days shout out at morning break, "Oh $h!t, I left my amp on this morning!" and sweating it until lunch when he could fly out of there, get home, turn it off and get back to the office.
I liked those Sherwoods, good stuff.
My cousin bought a Harman-Kardon in Vietnam, it still works. It has an SW section to it. I never got to check it out, no one is allowed to touch it but him.
