Default Re: Hallicrafters SX-25 Rebuild: New Mains Transformer Questions.

Round 1 of aligning my SX-25. Not sure how close until I try it out tonight, but I am sure I totally bolo'd the Hallicrafters instructions for IF/Phasing/Xtal/and BFO alignment. The rest of the set aligned well except for band 4: 30 MC was not reachable by my signal gen so I set it down to 28 and the set would not go past 26.5MC (trimmers).

The alignment seems to be pretty good, but I don't think its spot-on. This one seems harder than my SX-43 alignment (which was the first set I ever aligned).

I am sure I have many alignments in my future I'll be doing on this to get it right.

Anyone ever master the first part of the alignment procedure in the enclosed Hallicrafters document with some advice?
