Title: Hammond JR-20 Speaker Cabinet
Post by: EmperorNorton on June 06, 2015, 11:35:56 AM

Wandered into a moving sale very close to home and guy was giving away a Hammond Organ and the JR-20 speaker cabinet. I have already hauled the cabinet home and getting the organ tomorrow.  That will be a heavy move.

Not sure yet but google turned up this.....

that's about it, I think.  There are a 10 tubes in the cabinet along with 5 speakers,  alnicos, if original. 

I think the organ is a B-3 and guessing there should be a few more tubs in it.

At a glance those look ceramic, but it certainly could just be a larger bell over an ALNICO magnet.   Certainly looks to have potential, especially for the price.   The iron looks wicked!

Organs typically had 6SN7's as "tone" tubes and in the amplifier.  That's why they are plentiful and cheap.  Probably RCAs or Sylvania.  That should be a great sounding amp!
