As a followup to the output transformer installation and circuitry corrections, I installed the loop antenna, chassis and speaker in its cabinet yesterday. My evaluation of the unit is that although it has good sensitivity on all bands, the bass response of the replacement audio output transformer is woefully inadequate. It is only moderately better than a table model with a 4-5 inch speaker. I suspect that the original owner was very disappointed when he got his radio back from repair when the original transformer failed and had to be replaced. I plan to continue searching for either an original Philco transformer or find a better replacement with more iron in it. I had my misgivings about the replacement transformer the first time I spotted it.
