37-630 code 125 missing all 110 pF caps
#38

I finally got the chassis all back together and playing. It plays quite well even before the alignment. The only thing I’ve noticed is with the tone and volume control. With the tone control, the first and second positions when turned on sound the same with no change in tone when switched. The third position then cuts out the high notes. The schematic shows a weird setup though where nothing seems to be connected to the second position. Then with the volume control, it has very low volume (albeit smooth volume) until I get to what I believe so the tap on the control and then the volume increases dramatically. It’s goes from very little to booming volume instantly at one spot. Will give it a full alignment and double check my wiring. Don’t know it this has something to do with the tone control as the volume pot is connected directly to the tone switch… the only other thing is that I did add the missing 110 pF caps. Maybe the one off the volume control is pulling the volume down until it hits the tapped section and then jumps back to normal??
