Marantz 4430 Quadradial 4 Receiver
Marantz 4430 (1972, MSRP $499.95)
This beautiful Marantz came to me by accident. I'd responded to a Craigslist ad for a Marantz 2270 (a receiver I've been looking for), but when I arrived in San Francisco's Mission district, the seller pulled this out. I pointed out it was a 4430, not a 2270 as she had stated in the ad. She apologized and blamed it on her ex-boyfriend. Of course, I couldn't leave such an nice silver faced Marantz behind, so here it is after a few hours of cleaning.
