Re: Emerson Big Miracle
Cleaned up chassis. Restuffed capacitors as they were all very leaky. Piggy backed resistors to correct the 100-300% value drift. Made up a fake dual electrolytic and a missing tone correction capacitor. replaced a 6D6 with the correct 6C6. T-cut the cabinet and celluloid window
To maximise gain this set uses very high anode loads and screen feed resistors so any leakage will kill it. Not knowing what was original I have restuffed some late 40's replacements and the electrolytic, modelled after a pic on the internet, was also probably a replacement.
It works OK but I am getting a painful amount of fading on MW at the moment and of course there is no AGC on this simple TRF. Talk of over driving components, the service sheet indicates the rectifier has 126V on the cathode and the electrolytic is specified as 100V (just as well I went for a 160V part).
The knobs are wrong and I should make up some that look more like the originals but I will allow myself to move on to another project!
