Philco 90 - Tuning Gang?
#1

Hi all,

I have noticed in restoring my recent Philco 90 chassis that the tuning gang has a copper braid wire soldered to the three mounting bolts, which is then soldered to ground. Obviously this was a means of providing an additional ground to the tuning gang frame. But why? Icon_eek The tuning gang has three rotary wipers that have wires attached to them that are soldered to ground under the chassis. The other 90 chassis I did, did not have this braid wire soldered to the tuning gang bolts.

Has anyone ever seen this before? Is this a factory installation or did some repairman along the way decide that this was a good idea? I'm just a little curious about this. Both chassis seem to work fine without the braid. I had to remove it to install new grommets. I have not reinstalled it as of yet. I'm waiting for opinions.
