FOR SALE: National HRO receiver with serial number X-199 (1938). It is in very good condition mechanically and electrically for a 77-year-old radio. The four standard plug-in coils have the same serial number as the receiver, and they come with the National coil case. The 10-inch National speaker case is in fine condition, but the speaker will have to be replaced. (I use the 3” communications speaker shown in the photo). The power supply case (Velvet AB - 5897AB) is the one that came with the receiver, but the supply itself is a later model 697 (1946?). I made the switch because the original transformer seemed to me to be running very hot.
The S-meter is intermittent, but everything else seems to work. The receiver may benefit from an alignment. I have the full set of the original 2.5-volt tubes and some new 6.5-volt replacement tubes, which may be purchased by the buyer. The receiver is being sold as-is due to its age.
Asking $650, pick-up only, because it is too heavy for me to wrestle with. It may be the nicest HRO of that vintage available. Please email questions to K1CM a t ARRL d o t net.
