Ok. Fourth revised 70 mod schematic posted in posts #1 and #9 above. We can now assume all resistors are 1/2 watt except as noted in the modified schematic, and except for B-C resistor (37).

Since Ed's 70 has the filament center taps connected as per original factory wiring instead of what he shows in his drawing, I have left the filament taps alone. I may, or may not, experiment with this once I get my 70 going to see if changing the filament center taps makes any audible difference.
