Philco 40-180 hurdle
2/17/2007 6:15:55 PMj tamargo
I am new to this restoration thing & ran into a bit of a problem. After removing the pushbutton assembly, I was interupted and had to come back to it. I now have 3 green/white wires needing to find their way home. 2 of which are coming from the tuning condenser, and one from the 7 j 7 tube. I am not literate in reading schematics, so any help would be greatly appreciated. Next time I'll take a photo, Fiddlestix!

Shame...shame...shame.... as Gomer Pyle used to say...
Heres probably the best that I can offer without an actual eyeballing of the unit. Pending that you can see the fresh solder of where the wires were disconnected...better to just snip them with abou a n 1/8 in of wire snippet left as a marker as well as its color coding. If I interpret your info, you have the two wires from the variable tuning condenser
that were connecteed to the tuning unit. I have an accompanying markup with the Tuning caps sections 21A and B
enclosed in green and fuscia channels to the point where they connect on the manual/automatic tuning switch clusters
connection points.
As for the 7J7 wiring up to that cluster, two routes are possible since you did not give that tubes pin number.
If off the plate , trace down the blue zig zag route and you will see that it terminates into a silver mica cap, now I think that this is probably not your wire of concern.
More likely it is the the zig- zaged grid wires route (done in red) that terminates to two contacts on that switch cluster.
That accounts for two wires coming from the tuning capacitor and one from the osc section of the mixer...7J7.
Pull out yer ohmmeter and CHECK IT OUT ...as they say...

Thanks for responding,

I got it back up and running. On my next project, ALL connections will be marked! Hard lesson learned.
