Hi Richard,
?
I restored a S-40B a couple of years ago.? The advice provided already is of course very sound.? A tactic I like to do is replace the bulk power supply caps first and then fire up the radio and see how it plays.? It sounds like you've done a power up and it's generally working.?
?
Another thing to note is regarding the RF alignment.? There are holes in the bottom of the cabinet to facilitate tuning, and this must be done with the chassis installed in the cabinet. It's quite tricky because you can't really see well.? I was able to shine a flashlight in adjacent holes and I was still barely able to see what I was doing.? Maybe you won't have to mess with the RF tuning at all.? If you do, it would be helpful to get the lay of the land first with the cabinet off and maybe even do some rough tuning if necessary.? The coils all have beeswax seals.? If you are going to adjust them, it would be helpful to find the slots before the cabinet goes on, do the tuning, then remove the cabinet and re-melt the wax with a heat gun.
?
It's a good radio and the internal speaker sounds quite nice.
