After cleaning out Mom's basement after a mini flood I came across a Harman Kardon A230 tube amp. A quick look on the net told me it was from the early 1960's. Dirty, very dirty, but all intact. I was considering referbishing it with what ever it needed but I know nothing about the amp. Anyone with any experience with this tube amp or similar? Just wondering if it is worth the time / money to bring it back. Thanks in advance!
