37-9 poor reception at low frequencies
#1

All electrolytic, tubular, and Bakelite caps are new. Also new tuner support bushings. There is some reception at the higher end of the AM band, none below about 700Khz, and none that I can tell on SW bands.Cathode resistors on 6A8 and 6N7 check ok. R2 OK.
I am able to force a signal from my generator, perhaps it just needs a better antenna than i'm providing. Open for suggestions at this point.
Thanks
Cornell
