I have a Stewart Warner R-136 chassis it is also labeled model 1361-1369 Ferrodyne.
Alignment and Schematic http://www.nostalgiaair.org/PagesByModel...020359.pdf
Riders 7-4 & 6-18
Tubes all tested good
I have recapped and replaced all the dog bone resistors that were more than 20%. #13 a 300 ohm resistor was missing and the set would do nothing until I add that resistor.
Now I do get one very clear station 680 a number of weaker stations throughout the dial. I should get 750 as this is a big station here near Atlanta but I can barley hear it.
I have followed the instructions for the IF alignment and the broadcast calibration and b'cast band alignment but get no where. Have not tried any of the SW alignment.
One of the questions I have is there are 3 terminals on the back A,D,G currently D&G are shorted together with a clip. Should I leave this in place for the B'cast band cal?
I did not look at the Mica caps should I?
