NOTE TO ANY POOR SOUL WORKING ON A 38-10: Part no. 21, the 51K resistor, is INSIDE the IF transformer can. When you take readings for the secondary winding of the second IF transformer, they will always be the actual winding value, in this case about 8.2 ohms, PLUS the 51K resistor! This threw me, and I wondered if my transformer was bad, until I took it apart and saw the resistor inside, and measured across the actual windings, which were both good. I wondered if part no. 21 might be in there, and now I know. Note well anybody who works on these radios; if you get a weird reading on an IF transformer, look inside the can before you freak out. Philco may have hidden something inside. OH ! and that brown paper is held by a resin or wax that melts with heat. Just warm it up gently, and it will peel open, and then warm it back up to seal it back closed.
