smoke escaping from resistors
#3

According to the diagram you posted part #7, the 200 ohm resistor is a cathode resistor, one end goes to ground the other to the cathodes of the 6A7 and the 78 RF tube, there isn't anything there that would obviously cause it to smoke if it was wired correctly. Part #62, is a 50,000 ohm resistor, it looks like it's paralled with a 2 mf capacitor/condenser, that could be related to it smoking but I'm not sure why, if anything the 2 mf shorting out would burn part #61, the 32,000 ohm resistor since the cap is in series with it and ground.
Regards
Arran
