"Cut the cord" is good advice...some people never do!

When I was around 12 years old I used to work (play) around with radios like these and other tube units. It is a miracle that I am alive today.

The larger tubes without the keyway, sometimes had 1 or 2 pins larger than the rest. I agree on cutting the cord. I'm currently working on a Philco and I recently cut the cord, aside from it being in the way, the cord was junk anyways.

I'm with you on this. Always change the old leaky components and the so called death capacitors. Always use an isolation transformer on first test and a dim bulb tester. Also keep one hand in your pocket and play with your "loose change". I am in the UK and line voltage is 240Volts AC and some of those early sets used high filiment voltage tubes and dropper resistors without a power transformer. They can bite you hard if you make a mistake. Preserve these old sets and stay alive whilst enjoying a fantantastic rewarding hobby (occupation). Great video.

That was fantastic. I’ve probably restored about 8 radios so far and a whole lot of old VT test and measurement gear. I’m not new and I have a lot of current electronics design experience. Yet, I watched this and learned a couple things and had several things I knew become far more clear to me. I’m a person who is much better off once I really understand things intuitively and haven’t just memorized rules and charts. Well done and I look forward to watching more. Thank you for doing the video. I can only imagine how much time these things take and I really appreciate you doing it.

Hello how are you. Try this out: replace the power cord with a polarized and directly connect the neutral to B- if its a floating chassis or if its a true hot chassis connect neutral directly to chassis ground. Connect the hot directly to the rectifier and now the radio comes on when its plugged in but hold on this is what I do: the place where the original power cord goes to the power switch....you want to connect that terminal so that it only disconnects the heater neutral. Most of the time the last tube is the 12AV6 on miniature tubes but trace down where the last tube in series goes to neutral and disconnect it's return from B- or wherever the return goes and wire it to the switch. The radio will fade away slowly as the heaters cool also it will safeguard the piolet light from abrupt filter capacitor charging. If the radio is wired original and has a piolet light and is on and playing and you reach over and turn it off for two seconds and back on the piolet light could blow out from the charging surge unless you wait until the rectifier cools off for 30 seconds. It will have a slight hum when the heaters only are switched off until it fades

So true! Great video. I actually created a warning message 'template' that I send to every Ebay Seller of an old radio where it states that they "tested it and it works"....I even link this video. Its amazing how many people have no clue about this and plug this old gear into the mains to "test them out".. We should all spread the word.

Really looking forward to the rest of this series. I know a lot of it already but it's been ages since I've fooled with old tube sets. And of course I learned what a "hot chassis" was over 50 years ago via the usual way...

I’m not a great fan of AC DC sets as they call them here. They kind of make sense for use on a 120V supply where you may get a tickle. But on this side of the pond operating from 230V supply they have a large mains dropper resistor or a curtain burner resistive line cord. They run very hot and the live chassis can be lethal. I enjoyed the short appearance of the death capacitor

They flourished over here in the early days because many farms had 110 volts DC not AC coming to the farm.

Did he have an old Hallicrafters radio? Those metal cases can be deadly if not restored and isolated.

Hot chassis sets usually had wax plugs where metal screws were needed, such as the grub screws in knobs.

Cameras shutdown for many reasons. But, at least two are in your control. Over heating the sensor. Solution is to take time outs to allow cool down. There is a timer that shuts them off if they were sold as “photo” cameras to avoid a “tax” or “duty” issue. Same solution. The problem is that the shutdown time varies depending on the negotiation of trade barrier. Experiment.

Great video, yes I cringe every time I see one on Ebay and it says it has been plugged in and "lights up". Rotten wiring is a real issue as well. I have gotten some that would have gone up in smoke had they been plugged in due to rotten and shorted wiring.

The weight of the radio can be an indication there is a transformer installed. Just a tad bit more steel in there. When you restore a radio do you add a safety fuse? I would think that replacing a $0.50 fuse is better than a $40.00 rectifier tube or an unobtainium power transformer.

Well your explanation did not really help me it was too technical I know you were trying to make it not technical but I don't think you know how to explain it in a non-technical fashion. I just found an old radio 1947 Arvin model 544. I won't plug it in. I don't want it to go boom which I think is what you're trying to say in this video.
