Sparton rebuild

[mashaffer]

Well I got all the caps done and hooked up a speaker, PS choke, OPT and the antenna. I can not get higher than 93V in before going over plate voltages on the schematic but I have traced it down to my choke having much lower DCR than the original speaker field coil.

Never the less I ran it for a bit with the variac set to keep things in line and ran an iPod into the phono input. It sounded really quite good for the test lash up I was using (guitar speaker with no enclosure). I could not get any radio reception but was getting some static in places. Will see how it goes once I have the voltages all nailed down (heaters are running at 5V right now). It may end up needing an alignment of course given the extent of parts replacement involved. Will have to get the Heath rf generator recapped before I try an alignment.
