This is the full setup from a 1950’s Collins brochure.
Here is the 75A-4 which I have and love . . .
Here is the transmitter – which I would buy of a pristine one fell in my lap like the receiver did . . .
Here is what I have been told is extremely rare – the station console
I also have a brochure for another Collins trasmitter, but this set of “Gold Dust twins is one of the most famous and beloved ham radio setups – and they still compete with todays gear. As far as “user interface” is concerned – I think this set could be the best ever. Digital interfaces just don’t have what this set has. Its hard to explain – but a direct, “tactile” and nicely laid out interface beats menu driven interfaces.
