37-650: BREAKTHROUGH!
#1

Finally- something positive to report! Based on my discoveries mentioned in my "Goofed" posting, I replaced the three incorrect capacitors, put it all back together, and, after a little tube swapping, and realignment work, I can now say I do have operations on both SW bands and the entire BC band!

(And literally minutes after I finished aligning the set, my frequency counter arrived, so I can make sure the RF generator is set up correctly...lol... Well, the frequency counter itself needs an overhaul... It must have sat a while: the usual radio issues, minus the mouse... I'll clean her up, and see what she does. )

So, the bands are all reasonably well aligned, I have definite reception, and I will put her back into her cabinet after a few hours run testing. I only had two brand new caps to put in(the third hasn't arrived yet) but I found I had an NOS Sangamo of the right value in stock, and it checked ok, so I put that in for now. I'll swap the other one in when it gives up, if ever.

I adjusted everything by the book, although step 3 for both SW bands was skipped: I have never mastered that one. Once I had BC working correctly, I tweaked the highest and lowest stations into proper position, and all the rest fell into place.

Thanks, everybody, for all the help!
