In 2017, John added front, top and side panels for the Alpha 77Sx and 77Dx. In 2016, John added U-covers (aka wrappers) for the same amplifiers. To solve this problem, John began manufacturing replacement front panels for the Alpha 374A, 76A and 78 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. Replacing the FT-817s power amplifier yourself: In the somewhat unlikely event that you do have to replace the finals in your FT-817 (being that the vast majority of 817 users have had no problems at all with theirs) it is worth knowing that a hobbyist with reasonable soldering skills, modest equipment, and attention to detail can, in fact, do the job his/herself. One need that immediately arose in the repair efforts was a replacement front panel for some of the Alpha series of amplifiers. John began servicing HF linear amplifiers professionally in 2014. fifty assemblies have been successfully integrated. John and Mac collaborated on the development of this board, and the rest is history.

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. In 2014, John was approached by Mac McCullough, W5MC, to develop a replacement HV diode assembly for his Alpha 77Sx amplifier.
