Yesterday did the cap block, spent about 1/2 hr.
Today soldered it in place.
Then did not know what to busy myself with, and did the recarb.
Five resistors are good, 1K and 4x100K, the rest had to go.
Some were totally out: 70K resistor fully open, 13K resistor in oscillator load open, few were 4-5 times the value. So I don't think this radio would work if I were to try it after recap - the oscilaltor would not oscillate.
And the screen greed voltage would be too high due to the open 70K #66 resistor, though it is possible that this would not fully cut the reception.
Well, tomorrow rebuilding tin can caps and tone control.
Then - power-up!
