Is there a way to know when the bias supply has died? Suppose you're sitting in front of the radio, it appears to be operating normally, and then the bias suddenly disappears (i.e. diode opens, cap goes out, etc.). At this point, you're simply listening to the receiver. What indication would you get on the xmtr other than the 6JB6's (or 12JB6's for TR-3's) turning red hot? It sounds like we need a klaxon alarm wired to the bias :-)
