philco 48-1283 wiring issue
#12

jtkmsms, hi. The pictorial from Nostalgia shows the R101 resistor connected between a 3 terminal strip and pin 5 of the 50X6. This, in and of itself, is going to cause confusion. R101 is the last of a string that move away from (downstream) the 50X6 yet for connection perposes it seems circles back! Going downstream from the 50X6 there should be a wire from pin 7 to one side of the "candohm" (jargon for canned ohms = wire wound resistor wrapped in insulating/fish paper and crimped in a metal strip) on the rear wall of chassis and on same side of candom the + lead from C101. There should be nothing else connected to either. Downstream (other side) of candohm should have + lead C103A, red lead from T200, wire to one one side of R101 and two resistors R303 & R404. Here lies the first problem as I can only guess from looking at pictorial where all the connections are made. I'm inclined to believe they go to the top/rear most terminal of the terminal strip nearest to 50X6. Some could go to the candohm itself as it has a large terminal. Another guess here, since pin 5 terminal not large most likely wire from there to bottom/front terminal of the terminal strip nearest 50X6. See if the wiring conforms to near or close to the above. That connection to pin 5 is misleading since there is a terminal strip nearby I cant understand why the went to pin 5 rathar than straight between top/rear terminal and lower/front terminal of that strip. Also pin 4 is not connected in tube and some tube charts show pin 5 as being connected to shield? Let me know how your doing. PL
