Félix - what a "spectacular" dial. Your work under the chassis looks great. I hope the RF alignment goes well for you and it solves the issues you're experiencing on the lower end of the BC band and SW bands come back to life. I'll be looking for your next video. Well done. Best, Don
RestoreOldRadios Thanks for the compliment Don. I really look forward to aligning this set. Like I said, I don't see any reason it shouldn't do it. Cheers, Félix.
I have that same model of Stewart Warner downstairs, as a matter of fact that was the first console radio that I ever bought. In any event I can think of a few reasons as to why the broadcast band goes dead at the lower end of the dial, the first being the IF alignment, the next being the oscillator alignment. First, have you investigated whether the dial is tracking properly, like are the stations you are receiving in the right place on the dial, like a 1500 KC station is at 1500 for example? If it is then the local oscillator tank circuit may have a problem, like a leaky fixed mica capacitor (Or it could be more then one since S.W is dead), a flaky resistor that opens up when power is applied, or that the 6A8 tube may be defective. Another possibility is that there may be a wiring error, like whoever was in there before disconnected some of the wiring in the front end, and reconnected some coils wrong, or left a wire or a component out.. I have made a habit out of removing phono jacks from radios that did not originally have one, it's very seldom that they are installed correctly and they can cause all sorts of problems like hum and feedback, etc. I also don't see any reason to have one since there are plenty of old radios out there with factory installed phono jacks, and for the ones that don't have one a phono oscillator or an SSTRAN transmitter can be used.
Hi, Thank you a LOT for your input. I will investigate in this directioj and check what you just said. The reason I am keeping the iPod input is that this is a customer's radio that doesn't have or want to have a home AM transmitter, and there are no AM stations at all in my city. He wants to be able to listen to music he likes, and not only after dark when the stations from the rest of Canada and the US come in relatively clear. I did correct the previous guy's erroneous installation of it, and it doesn't seem to be causing any significant issue now. Have a very nice day, Félix.
Félix-Antoine Gravel Phono jacks can be installed properly, unfortunately the after market ones seldom are. I've noticed that in radios that came with them as original equipment they tend to be very careful about lead dress, and they usually used a shielded cable. I think that probably the best place to install one in the audio circuit is through the top end of the volume control, with a switch to connect the jack in circuit and disconnect the front end, though sometimes they connect them to the wiper. An MP3 player or phone should work as it has a high level output, much like an old style crystal cartridge, though I don't recommend connecting either to an AC/DC set as there is minimal electrical isolation.
Excellent video Felix!! Love it
james Burdon Thanks! :D
All this time I didn't know you had a youtube or I would have subscribed a long time ago. Your English is flawless. Nice Stewert-Warner! Subscribed!
coolbluelights Thanks for the sub Daniel!
I really appreciate your support.
Cheers,
Félix.

Nice to put a voice with the face finally! Well done young man! Look forward to future posts!
jawspinkid Hehe! Thanks a lot Jeff.
Cheers,
Félix.
Great Video Felix!! Your English is perfect!! I also subscribed to your channel. I did not know you were on here!! Keep up the great restorations.
SuperKing1963 Thanks a lot for the support John! I really appreciate it!
Cheers,

Very well done. English is my only language and you do better than me. I have problems speaking, live or recorded.
