41-280 restoration. - TeslaNotMarconi - 07-17-2018

I have recently discovered an antique cabinet. I have always wanted to learn more about the evolution of electrical components. I concluded that this would both educate and entertain.

I am looking for a basic, or comprehensie, idea of what this endevour entails. What kind of test equipment is required? Any help or education that can be found would be appreciated.

Welcome!

By "antique cabinet" do you mean a radio? Or just the cabinet?

I have recently restored 41-280.

So. It would be helpful if you provided photos of what you have. Cabinet and, if there is the chassis inside etc - all the electronics, meaning the chassis - top, bottom, speaker and such.

41-280 is a simple radio but might present a challenge due to the rubber-coated wiring that may or may not be disintegrating in which case aside from repairing electronics you will also have to fully re-wire the whole thing, which is what many if us have done, and it is not a complex task, but it requires patience.

This is my thread about it:

You will need:

A DMM (volt-ohm meter), a soldering iron, a Variac is desirable, a tube tester is very desirable and in the end you will need a signal generator.
Also - wires, wire-rosin-core solder and such.

Good luck.

Have a look around. You'll find lots of help here!

I apologize for the mis-wording I did mean radio. I have acquired the meter and the iron. I have also taken pictures of the chassis and the cabinet. The knobs and push buttons are in horrible condition and the face plate seems unrecognizable,  but it is otherwise complete. 

Please send feedback.

If wires are not cracked, the restoration is pretty simple: change all caps.
If you don't feel like doing what I did, meaning re-stuffing the caps, it could be very quick. Bite out the old, solder in the new. When buying the caps, opt for axial type, this will be easier.

Thank you for your feedback Morzh. I would like to go about it the classier looking way. I will check the wires and get back to you.

Looks like you may have had some rodent action in the past. Hence the rust on the top of the chassis.

RE: 41-280 restoration. - morzh - 07-25-2018

The inside is very clean. The outside of this chassis lends itself to easy cleaning once all the tubes have been pulled.
