Nice restore project. I had an old Hallicrafter years back. I stored it when I was away on training and I think my parents tossed it out as it may have resembled a heavy piece of junk. I miss that old girl
Interesting but please add some more light. I have 3 of these SX 100 receivers and I want to see what problems you have before I start working on them.
If you find the volume low for no reason I have found on my SX-71 that in one of the IF cans the slug or rod has broken from the adjustment and it will not adjust..this has happened to me...and the only way I could get the volume up was to lean the radio to one side...took me a while to figure this one out...I had the volume down and I happen to hear the slug move up and down in the tube, in the IF can...
When you measure a resistor "in circuit" aren't you also measuring the surrounding resistances? UNLESS you have an isolation type meter...can youy coment?
I really love your videos of all the old Hallicrafters. I just got one of these sx-100 radios.

Hi Steve. I have never seen A crystal in a vacuum tube before. Cool. Nice set and great explanation.
All my best.

replace resistors with new metal film is good but never use them in rf circuits. always use carbon comp in rf. good rule of thumb.

Did you ever it it repaired and back going
