Philco 40-150 help
#8

Thanks morzh, Here is what I have found: When all connections at the junction of R59,R60,R44, and pin 4 of 1232 are disconnected, it is R59 showing the ground. (other side of R59 is grounded according to schematic). Disconnecting R59 at this junction cures the ground problem at neg of C61. Odd, R59 showed 15.2 ohms when connected, but now (disconnected) shows shorted; I will replace it and recheck. As for the C17; when that junction is disconnected, it is the red lead from the 1st IF trans that shows ground. Disconnecting red lead cures the ground problem at that point. So I guess I will look into that deeper once I replace R59. BTW, all tubes are out. I'll post back with my findings. Thanks for yours and Brenda's help! Tim
