AK 40 restoration

Hi, all.  My AK 40 is back together, and plays well, with good room volume, on my roughly 75 foot antenna.  My question - one of the audio transformers was open, so I replaced it with on from Antique Radios.  When I removed the old one from the can, by heating it in the oven, I found that most of the winding turns were not only open, but appear to have segments of each turn, about 1/2 inch or so, missing, completely gone.  Anybody have any ideas how this happened?  (They were not stuck to the inside of the can.)  Thanks.  Charles Stevens

My guess is that dampness in the tar corroded all of them open. You might expect more problems like this in the future. It was likely stored in a dam p place for a long time......

Bill - You're probably right.  The metal cabinet has some slight rust where the paint is chipped.  And in reference to your earlier comment, I have replaced all the caps in the power supply and in the main chassis, and all of the non-wirewound resistors.  On some of those I had to clean the ends of the turns and the underneath side of the screws to get the resistance to read the proper value.  Thanks again for your help.  Charles

I'm happy you got it working again....

Congratulations on your restoration! Please put up some pictures so we can see it.
