Awesome troubleshooting skills Sir. I live in Brazil and inherited an old Bush export set I been working on for 16 years! Besides the electronics your carpentry works are also top notch. Cheers.
Glad you are taking on this project! I restore radios from the early 1920's through the 50's. Tubes in these old units almost always work! There may be one our here or there on these sets. However, they are usually all good as are the coils and transformers. Just never power one up without changing the electrolytic caps first, as I am sure you know! Anyway, I just found you on UA-cam and subscribed and have just started watching this video. I'm sure it will be fun to watch! Best Wishes!
That model radio looks very similar to the one that was used in the British War Series "Danger UXB". You can see it in the officers lounge, they even listened to it occasionally.
OK, I finished watching the video. I see you do not have a valid schematic for the device. However, you did get it working. If you have a single generator, you can set the IF cans by ear. I would set the signal generator to around 600-700 KHz, (modulated at 400 to 1KHz) and make a small loop of wire with about 5 or 6 turns of wire. Lay that somewhere near the antenna terminal of the radio ( apiece of wire should help reception). You should be able to hear that with the radio on AM, and tuned near the same frequency on the dial. Then, starting with the IF can before the detector tube (2nd IF), try and tune the slugs by ear for max volume at the speaker. Then proceed to the 1st IF transformer. Repeat that process between the 1st and 2nd transformers to get optimum reception. As for an antenna wire (assuming you get it tuned) a single wire wrapped around the baseboard of the room or ceiling should give you some reception for the other bands as well as improve AM.
Greetings from Ireland. I aligned the radio ok with sig gen and scope, but found the peaking at 362kHz rather than the usual expected 455-460Khz. However as you saw, the main problem is with the low emission valves and overall a lack of any worthwhile reception here on an a.m. radio anymore. So with this in mind, I have decided to scrap the original format and revitalize the cabinet to contain a modern radio receiver module while maintaining the look and tuning mechanism of the original. The purist restorers will hate me for this , but what the hell!. I won't have some of the components arrive until January, but if you wait to see what transpires in the next episode I think you will be surprised (or appalled) Cheers, - Rod

Nice job on the case. Whatever you decide to do inside, it's going to look great doing it! 🏆

Fantastic restoration on the cabinet. The chassis???

oh shit, cool
I think youi meant R.I.P.
Ha Ha nice one!
