Another S-38C on my bench, part 1: Examination and Diagnosis.
Last year at Dayton, I had purchased an S-38C because I wanted another example, having had one when I was younger. Unfortunately, while I found one, it seems to have silver-mica disease. Really, really bad. So the hunt was on for another one.
I found this one at Findlay 2025:
It’s in decent enough shape. Back and bottom covers are present, even though the paper is deteriorating.
Inside, it shows a little work. Some new resistors, a filter that’s been resoldered, and a new power cord.
I’m going to replace the 6 tubular capacitors in this one so it’s somewhat safe to use. Of biggest concern, of course, is the bumblebomb present across the line. That absolutely must go.
Other than that, the filter is in good shape, so it stays for now.
Stay tuned for the next part of this series where we determine what parts we actually need!
