Some Philco 70 questions/ANSWERED
#9

Are there some changes to the early Philco 70, other than what's with the schematics? Mine works great and I'm recapping it. Since it works great, I could just ignore this, but I'd like some confirmation. The 5K resistor shown on cap block 12 goes over to cap block 5 on mine.The schematic and the parts layout show that 5K on the cap block 12 from one side to the other. Has this difference come up before?
