I have a Philco 89 late chassis which I just restored, with a problem that it receives well up to about 1350 kHz, then the dies out above that. I aligned it on a reference signal generator, and indeed it can be aligned at 1500 kHz, at zero dB, which is a very strong signal indeed. However it is too insensitive at that frequency to receive a broadcasted signal. With a quality antenna attached, it has no problem receiving signals up to about 1200 on te dial. In order to get this one playing, it was necesary to rewind the oscillator tube plate coil section, and the primary of the antenna coil. I probably have a little less wire in the antenna coil primary than the original did. All the tubes are good. The padder peaks up nicely at 560 or so. In my experience, loss of sensitivity at the high end of the BC and is unusual. Wondering if anyone has some thoughts about this. Thanks, Mike Schwartzman
