BOL question
#6

I got it to go down to 580 by adding a .003mfd across 7A.  Below that it just want to conk out (both w/push buttons and main tuning). When I got it Sam told me that he couldn't pick up his sstran on it at 1200kc and wouldn't pick up anything at high end of the band.

After giving it a cursory look over I noticed that when the pointer was all the way over to the left the tuning cap @ min capacity. Thought it was a little odd but some sets are set up in this fashion. After looking online at some pics of the cabinet I found that it was indeed tuning backwards. Somewhere in it's sorted past someone restrung the dial cord backwards. Fixed that and the intermittent off/on switch wasn't intermittent any more. One of those p/b style jobs. Replaced it.

IF peaked up nicely at 455kc and the SW band was working fine but the broadcast band would only tune down to about  740kc and die. Didn't have a 7B5 so used a 7C5 and that helped it would tune down to 650kc. By adding the 3000mmfd  I got to 580kc. Sam is sending a replacement osc tube and I'll see how it does.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
