    Tube Radio Restoration

    Hello, I would first say does any of the tubes get warm or light up? if they do, you got power coming into the chassis, however if all tubes or cold and none light up, I would see if it has a transformer (some do and some don't) like the one in this instructable does not. If you got a DMM handheld meter I would start by seeing if the wires coming into the chassis from the wall outlet have voltage. If It does, then see if the transformer (assuming it has one) has voltage coming out of the output side. if nothing is then i would say it has a bad transformer. sometimes the on/off switch is part of that circuit and may not be working either and you would know when its switched and has no voltage on either side. Now a radio that does not have a transformer you would do the same test only ins...

Now a radio that does not have a transformer you would do the same test only instead of the wall outlet wires going into a transformer, one goes to the on/off switch and the other goes to a tube. use the DMM at both ends to see if it has power applied when on/off switch is switched to "on". if it does have power the wires are good but the first tube the wires go to after tha are probably bad. Thats the same method i would try with either type of radio. Generally with a old unrestored radio, its the transformer, power switch, bad power tubes (most common and most easy to fix), and least likely would be a broken connection somewhere in the chassis so give it a good look over first then try those steps. Feel free to let me know how it goes. Thanks!

    Remote Controlled Styro Plane

    It doesn't bend much but it doesn't take crashes to well.

    I used a kit from another air plane. As you can see it didn't fare to well in a crash. eBay used to have them for around $40 which included control board and remote.
