Title: Hammarlund HX Fifty
Post by: sndtubes on February 26, 2010, 04:28:00 PM
Hi Guys,

I was just given a Hammarlund HX Fifty transmitter.  It's in nice shape, but probably need the usual re-cap job.  This one does not have the optional 160 meter kit installed.  The manual for the 160 kit looks straightforward and the parts are common except for the coils.  Unfortunately they don't give any of the values for the 3 coils needed, only Hammarlund part numbers.  Does anyone out there know what the actual values for these coils are?  1st Mixer is P/N 26786-21, 2nd Mixer 26786-18, and the Driver is 26796-19  I would assume that if I could find something in the ballpark for these coils, I could probably get 160 M to work.  Thanks as always, Mike WB0SND sndtubes@vacuumtubes.com
