Starting on Philco 111 More Questions & Pics
#37

OK my helpful gang. Here we go again. I will first say, due to your guidance, I checked everything in the area between the RF amp and the first detector. All wiring (remember I didn't remove any and the parts I put in appear to be fine. Next on to the coils which I thought looked ok before. Well, it appears the primary is open on the detector transformer item 9 on the schematic. The smaller coil on the primary looks good! I have checked it and checked it again with my dull bulb brain, it really appears to be open. Well I tested the radio again and it still works, or should I say with a short antenna I can receive my SStrans and a local. Don't know how that can be? I always thought "going green" was a good thing. Well, I guess Philcos have their problems and the "Z" brand has different ones.
At any rate I will be looking for a replacement one for this these or someone with the mental, visual and manual skills that might help. Still not certain how this would be doing if it is open and allowing the radio to work.
I have attached a picture of the output of the receiver on my scope with antenna shorted out and volume high. This is taken from the speaker, on my scope. You can see the spikes that are really quite loud at high volume but less noticable when on station. I can still hear them.
Am I doing something wrong?
Thanks for your expertise.
Jerry
