Heathkit AJ-1510A Display Replacement

 
The AJ-1510 and AJ-1510A are one of the first synthesized FM Stereo tuners to be introduced in the 1970's.  Today, these units are not only nostalgic tuners   from the golden audiophile era, but they still have very respectable performance.  The biggest problem in keeping these operational is display failure.  These units were   designed before the advent of LED displays and utilized a 7-segment filament type display in a glass tube.  Over time, the fragile filaments will break causing one or   more segments to no longer light.  These displays are almost impossible to find.
 
 We have several of the AJ-1510 FM Tuners and to help keep them running, we have designed   a replacement display using newer LED type displays.  The modification consists of two boards that replace the existing driver board and displays.
 
Each kit contains all of the parts that you need to convert your AJ-1510 or AJ-1510A FM Stereo Tuner from the original displays over to modern LED displays.  It is also  possible to reverse the modifications and go back to the original displays, should you ever decide to do so.  It takes about an hour to build the new kit and replace the old  display board with the new one.
