Raleigh, yes. I wasn't sure if they did that just for alignment, or possible output to another speaker with the main speaker output out of circuit.
Interesting on the the other comments. Since I don't have the cabinet here, I am going to take this and install and recheck the hf osc. I hope I can reach the two on the left (from the back) front if I need to. I suspect the BC will change much, if at all. It tracks perfectly the way I have it now.
Terry, I bet you and BAD are right. I tuned my Icom 746 up and down the same range the SW bands are on the Philco and hear one carrier or something every few kcs. Now if I can just get the hf osc on the 9 to 12mcs band to align I'd be done. Something is not right with that. I am unscrewing the trimmer way out to get what appears to be the fundimental on my SG, but hear two signals about a kc apart that about equal in strength. Only thing I can see different in the osc to speak of between SW1 and SW2 is an 84pf mica which I replaced, in series with the tuning condensor. I got a new 82pf (checked) which should not have made that much difference, but it may have changed since I put it in there. I've got some 2pf ceramics I could parallel with it, but not sure I should put a ceramic anywhere in the osc. section... Could try it I guess.
