i just salvaged a pair of 10" speakers out of an old hammond chord organ. the only marks are tree sets of numbers inked onto the outer rim that read "9352", "285747", and "AO-26689-1" on one, and ""9353", 285747", and "AO-26689-2" on the other. they look like some of the old jensen speakers, but i'm no expert. they appear to be in mint condition, and i salvaged the baffle and grill cloth also. if i built an open back cabinet, could i run them off of the extention speaker output on my 70's vibrolux reverb? thanks, john

Have salvaged a few speakers from Hammond organs. The old Hammond Chord organ has two P10R Jensens worth a whole lot more than the organ!!

The problem with some of the Hammond speakers is that the paper cone on some are just too thin for guitar use. The VERY thin paper cone speakers are used in the reverb amplifier and don't really hold up when hit with a guitar signal. If you can find some Jensens they will be marked with a 6 diget number starting with 220.

What model of Hammond did you get these out of?

The "285" is the EIA Code which identifies
the manufacturer of the speaker as Rola.
The "747" could be a date code, as could be the "9353"
The "AO-26689-1" is probably a Hammond part number.<font size="1" color="#8e236b"><p align="center">[This message was edited by Blake Hawkins on 24 July 2005 at 07:33 PM.]</p></FONT>
