Early Two trimmer Philco 20
#1

I have an eay two trimmer Philco 20 that was restored about 10 years ago.
The servicer used vinyl wire and seems to have chenged the wiring layout..as compared to my later parts set 20 with three trimmers. 
I know some coil numbers changed but I was trying to find bulletin 28..could not find it on the forum. Did find the early schematic but only a coil change.
Does anyone have the early Philco 20 1 or 2 trimmer version? Or Bulletin 28.
I wanted to put it back to original...though it works..some parts dont match up.
Photos and a bulletin helpful. Thanks

I found that the wire insulation was burnt.  The fly back needs corona dope! Why would someone put that there?Platinumblonde36 — 01:09 AM
