Hello Vlad95 ,
Very Funny !

By the way.

Take a look here: Dial cord stringing Guides
May be here you can fount correct string setting.

Vlad, you nailed it. Swiss and German roots.

Thanks Rod,
"When you hear the background hiss and no station it usually indicates that the oscillator quit" probably my luck it has quit, and I don't currently have a signal generator for testing."
As for the tuning knob, not European but since the cable was broken when I received the radio the string must be backwards. And it's working perfect going the wrong way.

Vlad95,
Thank you for the stringing guides and wow there are so many

Hi OSanders,
Look carefully at the band switch. Turn it slowly and "wiggle" it around the desired band. Try the shortwave and preset bands. Use Caig DeOxit D5 to clean the contacts. The stuff is not cheap, but it works very well on switches. (Do not use it on volume controls; use DeOxit F5 fader lube instead.)
If you do not have a signal generator, you can use another radio. Tune the radio to a station that you can (or could have) receive on both sets. Have the sets close to each other with shields on the convertor tubes (if there are any) removed. u can (or could have) received on both sets. Tune the radio in question through the band. at some point, equal to the set frequency of the good radio + the IF frequency of the radio in question, you should hear changes in the signal on the good radio. If this occurs, the oscillator stage is working.

Ok MrFixr55,
I have tried the DeoxIT D5 on the band switch and even though it has relieved the tension I felt when turning the knob, I still wasn't able to receive any broadcast. As for testing the Oscillator using another radio, I don't have another old radio but tried with one that I had which received AM stations and didn't notice any change in the signal while tuning the Philco.
Figuring out the Oscillators on the parts listing is confusing, looking at the chassis and schematics it looks like #14 (Broadcast and SW) also 15A-B. Which would be the main Oscillator I need to check?
I am now checking the wiring and contacts in the Oscillator area to see if anything may have shorted. The backside of the switch/contacts (where it protrudes through the chassis) seemed to be the worst before using the DeoxIT.
RE: Philco 42-345 Restoration/Repair - osanders0311 - 06-17-2025
So far still no broadcast, I am posting pictures of #14 Oscillator and also a resistor #27 which connects to an XXL tube and the band switch. I am replacing the resistor and will give an update after replacement. Looking at the enlarged picture of the Oscillator I'm not sure if it may be bad.
RE: Philco 42-345 Restoration/Repair - osanders0311 - 06-17-2025
Please tell me this was it, I replaced resistor 27 and it's playing on the broadcast band. I am afraid to change the band
but I probably should try the others.It reminded me of having a tooth pulled, it was really tight between the 2 terminals.
RE: Philco 42-345 Restoration/Repair - Paul Philco322 - 06-17-2025
I have that same set, ain't too much shortwave I like anyway.....it is a good AM DX set. Paul
RE: Philco 42-345 Restoration/Repair - RodB - 06-17-2025
What does the resistor measure? I think it should be 3.3 Meg.
If the oscillator coil has continuity and the resistance measures close to what the schematic shows then it should be OK.
RE: Philco 42-345 Restoration/Repair - osanders0311 - 06-17-2025
The resistor is a 2.2 Meg, it was the last one I hadn't replaced. The broadcast is coming in after replacing it.
RE: Philco 42-345 Restoration/Repair - osanders0311 - 06-18-2025
We'll guys this radio played yesterday and until this evening, I even had the owner stop by to see all I replaced before inserting the chassis back into the case and it played good during that time. So, I put it together and built myself a loop Antenna which to my surprise worked very well. Unfortunately, there must still be an issue with the band switch, and I know I've switched it earlier, but I believe only while the radio was off and had no problem after turning the radio on. I took a chance while it was playing and switched the band and that was it. Again, I cannot get it to pick up any broadcast, so the chassis is out of the case. I have sprayed more DexIT and closed shop for the evening and start out fresh tomorrow.
Here are a couple of pictures of what I thought was finished.
I like how my home-made Antenna just slid out of the case.
