Welcome to Tech Talk and the 1A2 and Comkey forum. If this is your first visit, we appreciate your taking the time to read this message.
There is a lot of information to be shared here but all we ask is that you have your profile completely filled out. This way, we know who we are helping.
1A2 often deals with higher voltages than today's systems that can cause a shock and possibly injure you. We don't endorse end users attempting their own repairs. We will assist you as much as we can, but please don't ask us to assist with wiring or hardware issues unless you have some level of telecommunications hardware experience.
There are plenty of old-timers here who have plenty of experience with these systems, so just have plenty of details and we will do our best to assist you.
