Very Vintage receiver with a interesting history. I have always admired National. Had a few as a kid. Always wanted a clean NC-173. I have owned many, but none as nice as this one. Lucky find, from the original owners estate. Came with the original manual & speaker. Problem was due to age, the tuning dials became dark and un-legible. Did a bit of research and found that Radio-Daze makes reproductions on a special order basis. Installation is quite the task. Requires removing the chassis from the cabinet. Lots of cleaning & lube to ensure smooth operation. It is a labor of love. After getting the receiver operational, I installed a 1MHZ crystal calibrator and safe standby switching module. Now the receiver is ready to team up with a classic AM transmitter. If you want either of the modules featured or have questions regarding repair of the NC-173, drop me a line.
