Man, I love those vintage set-ups!
Here's a pic of that beutiful Pioneer . . .

Two nice things about those recievers are . . . they are becoming very collectible and can get some decent $$$ . . . and they are refurbishable with a number of places that will clean them right up (solder, caps, noisy dirty contacts, lights, etc)!
Keep it rock'n and don't part with them, unless you want to give me a call. ;\)
