The SX-1250 is one great receiver. I have fully restored mine and it really sounds good. Really good...worth every hour of work done. There is a good thread over at AK about recapping these, and it includes a couple dozen transistors that need to be replaced with better, lower noise units.
After I did that to mine it was a different receiver. It went from meh, ok...to KICK ASS.
I got mine for a very, very nice price...it was in the trash across the street about 15 years ago.
