Hi Terry,
I verified voltages again and I got the following measures:
** Values in parenthesis are the expected according to wiring diagram http://www.nostalgiaair.org/PagesByModel...013633.pdf
3LF4 1 - 7 : 1.49 v
1 - 8 : 2.74 v
7 - 8 : 1.25 v
7 : 120 v AC (77 v AC)
2 : 84 v (72v )
3 : 87 v (74v)
6 : 1.6 v (~9v)
1U5 1 - 7 : 1.71 v
2 : 25 v (9v)
3 : 14.9 v (16v)
4 : 1.6 v
6 : 1.1 v
1T4 1 - 7 : 1.42 v
IF Amp 2 : 87 v (76v)
3 : 65 v (45v)
6 : 3.4 v
1R5 1 - 7 : 1.74 v
Converter 2 : 86.7 v (76v)
3 : 65.1 v (45v)
4 : 0 v (0.5 - 2.5v)
6 : 0.76 v
1T4 1 - 7 : 1.66 v
RF Amp 2 : 86.6 v (76v)
3 : 65.1 v (45v)
5 : 3.4 v
6 : 0.2 v
I am following the 48-360 wiring diagram since this radio uses the 3LF4 amplifier and after checking the wiring it fits that wiring.
Regards!
