I hope someone can help me.
I have been trying for some time to perform the alignment and test, Part 1
(Page 36-39) for the receiver.
The difficulty seems to be U1 and U2. I have determined the voltages with and
without T1 and T2 installed, they are as follows:
With T1 and T2 installed the voltages are:
U1 U2
Pin 1 0.55 0
Pin 2 0.55 0
Pin 3 0 0
Pin 4 6.08 6.08
Pin 5 6.08 6.08
Pin 6 6.03 6.03
Pin 7 5.38 5.38
Pin 8 6.08 6.08
With T1 and T2 Removed the voltages are
U1 U2
Pin 1 0.55 0
Pin 2 0.55 0
Pin 3 0 0
Pin 4 6.08 6.08
Pin 5 6.08 6.08
Pin 6 6.03 6.03
Pin 7 5.38 5.38
Pin 8 6.08 6.08
I have checked the toriods 3 times. Verified the PCB traces. Also, when I
touch pin 4 of U2 I received a very strong AM station in the area.
Thanks for any assistance.
