Product 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 successfully installed.

John began servicing HF linear amplifiers professionally in 2014. One need that immediately arose in the repair efforts was a replacement front panel for some of the Alpha 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 374A, 76A and 78 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.
