[Hallicrafters] Hp 11710B down converter

[Jim Liles]

We have a used HP 11710B down converter that we don't use and possibly a 
pair, new in box.  The used 11710B works properly and we ask $115.00 + 
shipping and the new in box $200.00 + shipping.
I had several that I disassembled for a pair of hard line relays and other 
parts.  We used an HP 8640B, down converter, and ramp generator for 
years --- the ramp generator fed to the 8640B in FM mode makes a great sweep 
generator and the down converter gets you to 10Kc.  Kindest regards Jim
