Alpha Legacy Products – History

In 2014, John was approached by Mac McCullough, W5MC, to develop a replacement HV diode assembly for his Alpha 77Sx amplifier.  Mac had just upgraded his amplifier with a new transformer and capacitor and wanted to replace the high voltage rectifier board with a modern, up-to-date design.  John and Mac collaborated on the development of this board …. the rest is history.  Thirty assemblies have been installed.

John began servicing HF linear amplifiers professionally in 2014.  One need that immediately arose in the repair efforts was a replacement panel for the Alpha 76A and Alpha 78 series of amplifiers.  A problem with the original paint used on many legacy Alpha amplifiers leaves the panel gooey, sticky and prone to scratches after a few years.

To solve this problem, John began to manufacture replacement front panels for the Alpha 76A, 78 and 374A amplifiers.  In 2016, John added U-covers, or wrappers, for the same amplifiers.  In 2017, John added Alpha 77Sx and 77Dx front, top and side panels to the growing list of products.
