The nomenclature is lost in my memory but the description is exactly right. We didn't open one of them up to look inside because they worked really good and no one wanted to "Fix something that wasn't broken" The transistor remark was off the cuff. Lots of radio receivers were getting smaller and smaller using transistors then.
In spare moments we would hook one of these up to a 100 ft inverted "L" longwire and "Talk" to the hams on the MARS network. They were usually talking to each other vocally. We would try to "Break" using our CW. Once in a while we would get a response. One guy copied our CW and answered us in voice. That was cool!
The little guys had lots of power and worked great. This was in 1968. At 71 I really have a bad case of CRS. Thanks for the info.
