Well, to give them a little slack, it is a radio (circa 1936) and I guess some people figure radio has been around forever

. I'm not sure however whether correcting the seller in this instance would be condusive to my getting a better deal or not (or any deal at all). I guess I'll wait and see what they end up asking (no price on the ad). If they're thinking this thing might be going to make them rich, perhaps they'll be due for a nice humbling lecture on vintage radio.
I bought a Sony STR-V6 not too long ago and they guy was claiming in his ad that the thing was 670 watts. I knew he was reading the power consumption from the sticker on the back, but didn't have the heart to correct him. He was only asking 40 bucks for it anyway so I told him it would blow my speakers away (and I wasn't lying because its actual 120 wpc will indeed do so if I'm not careful).
