Beautiful Vintage Hammarlund HX-50 Tube-Type Amateur Radio Transmitter SSB CW AM
Price: US $560.00
Beautiful working Hammarlund HX-50 dating from the 1960\'sRated by the manufacturer at 50 to 60 watts output on SSB and CW (90 watts input) and 12 to 14 watts out on AMThis vintage Hammarlund was the home station of W5NVT, a Silent Key. It sat for years on a shelf in his office in his store, then after his death has sat on a shelf in my hamshack for years.I cleaned it up a bit for this listing -- 4 tubes were replaced as they had low transconductance. I cannot check the 6C10 Compactron as my Hickok tube tester is too old.The transmitter was brought up slowly on Variac over several days -- and tested on cw and ssb on the 40 meter band. Good output and good sounding audio and cw signal.Note: this is a really heavy \"boatanchor,\" weighing 47 pounds before packing and carton weight are added. The unit will be very carefully packed for shipment. I\'ve included a $10 packing charge anticipating that having it packed by FedEx or UPS including carton purchase will likely cost about $20, so I\'m asking the successful buyer to share in the packing cost with me.This transmitter is guaranteed not to be dead on arrival.A spiral-bound copy of the operating/service manual is included. The manual is either an original or is one of the best copies I\'ve ever seen!Important: I recognize two modifications, both reversible. The 5R4 rectifier has been replaced with solid-state diodes and a suitable dropping resistor added to compensate for the plate resistance of the 5R4 so that the B+ won\'t be too high, and an additional filament transformer has been added under the chassis. Also -- a second OA2 VR tube has been added -- in such a professional way that it appeared to be an original stock item.There are many modifications recommended for the HX-50, many of them authorized by Hammarlund. I\'ll include a CD with a number of them -- some of them may already be incorporated, and the winning buyer may wish to make additional upgrades/enhancements in stability, power output, and ease of operation (VFO spotting).If you can arrange pickup of this item in Albuquerque, NM, there will, of course, be no packing or shipping cost .
