Hello friends. I took some time today to relax, fix an old Aircastle AM radio that I picked up a few years back. A great Hamfest find. This model is fairly uncommon. It is a hot chassis radio, so you have to use extreme caution when servicing. The focus is on th Aircastle, however you will find most radios of this era are similar in construction, thus sharing the same failure modes. Hope you find value in this presentation.
