Philco 112X restoration
#5

Thanks Arran.  As you can see, I did put a fuse holder under the chassis but it is not the typical low voltage automotive type.  It is a Bakelite, high voltage holder as has been used in some of the organs I have serviced for years.  I'll look into the fused plug, though.  that may be a neater, simpler solution to protecting things in case of a TR failure or something.  For the sake of safety and to avoid the 60 volt tickle, I've often considered a 3 wire plug/cord connection.  I did that on one of my shop radios and I like not getting the tickle when touching the chassis.  Certainly not original, but...

As far as the adjustment on the end of the capacitor rod is concerned, these don't have that. it seems they relied on friction in the system, particularly the dial drive pulleys, to hold a setting. I know the bearings and the grounding "brushes" were lubed with something. it looks like it might have been some sort of graphite grease. For now, I put in some felt that rubs against the dial drum. that seems to hold the settings.

The radio is working great even with very weak tubes!
