Pull it out of the heap and had a look at it. Kinda crusty but all original. Spent an hour or so replacing 3 paper cap and one bakelite a 3651YU (#16). That one has two caps in series a .05 and .03. Anybody got a wiring diagram of it?? Pretty sure I've got it wired correctly but want to double check. It and two of the paper caps are fairly hard to get at there down between the oscillator coils and band switch. Wired in a couple of electrolytic caps and took it for a test drive. Makes rf but no modulation. Measured some voltages and they seem a bit low. Ac voltage from the rectifier plates to chassis 127v and 0V. Not good as half of the hv winding is open. Pretty sure somewhere around I have 125-0-125v @15ma transformer
