Always replace those electrolytic capacitors first before powering up a unit as old as this! You risk blowing tubes you may not be able to find anymore!
That's why I bring it up with a variable power supply and a watt meter. On these old molested machines I attempt to do a resurrection, not a full resto in the spirit of the style of videos Shango66 does. It is part of the learning process, starting at one end and working along from one problem to the next. I get to see what the different stages of each failure produce first hand. These are all student projects. Mistakes are the best teacher. You can bring this stuff up slowly before burning up anything if you pay attention to the current draw in most cases. This is a very common technique you can see done many times on many other repair channels. Check out the recommended channels on my front page if you would like to see more. Thanks 😃

@@electricalmagicsmoke thank you for your reply, it puts things into context. I am not electrically / electronically savvy but find blogs like the ones you produce very interesting.
I haven't made part 4 yet. I'm going to keep troubleshooting down the line until it plays or I prove that it never worked this way. I put it together after the recap. I am not getting full voltage to the motor. I plugged the motor in directly and it and all the mechanics seemed to work. I will try to make an update this weekend.
Is there still components missing off that other half of the chassis? Looks like a terrible butcher job your trying to make sense of there. If you have been able to identify that amp then you might be able to find a circuit diagram for it and help make better sense of the mess.
That would have used a field coil speaker. Looks like a PM speaker is installed. Maybe that resistor in the vented can was a replacement for the field coil.
Terrific keep it... I know you could do it. Thanks v much.Sir.

Why would you want to try any start up before checking out individual components?

I don't actually see a conclusion on this.

I am coming along on it. I need to get my butt in gear and make the next video.
You may want to change all those paper wax capacitors. A lot of them go leaky over the years.
Did you watch the video? Time stamp 11:56

nice :)
