Hi,
 
Selling my much loved F-1X. Installed in my home recording rack and has never seen the outdoors.  
 
Excellent condition, a couple of small scratches from changing positions in and out of rack. Original box/instructions and two unused russian Sovtek tubes included.
 
$550 shipped - lower 48 or Canada.
