Zenith H615 Tube Radio IF Transformer Repair - Silver Mica Disease

In this video I repair the Silver Mica Disease (SMD) in the IF cans of a Zenith H615 Tube Radio. Silver Mica Disease manifests itself as popping and crackling, and eventually can lead to no audio output at all. You'll see how I removed the old mica and trimmed the contacts. I start by showing the mistake I made when I first tried the process. This way you can see what to avoid yourself. Here is a link to the schematic of the IF cans themselves: http://meanmutha.com/zenithifxfmrs.gif
