>One of the items I picked up was that Atwater Kent 45. It is a strange radio for me because it is a TRF. I have been trying to do some research on TRF's and I took note this unit does not have manual regenerative feedback. I am not entirely clear on this kind of feedback or if it was typical in TRF's but I was wondering what it not being there means. Is it a good thing in a design and what might be the downsides of it, if any.

>Also the unit uses an external speaker. Of this I have no Atwater Kent speakers just lying around the house so the question begs to be asked, what do I do? Can I use a modern one with some transformer matching? What would the matching be? The Rider's drawings are rather vague. It doesn't even list the tube numbers on the schematic! But I have been able to pin down it is five 26's, one 27, and one 71A., and an 80. And is there anything else I am missing to bring this unit online other than the obvious recapping if necessary? As always, thanks.
