Some time ago I received an 84B for servicing,while checking I found the antennna and osc. coil open ,tried to rewind the coils without success and the owner was asking for his radio,as a very last resort I asked to myself:Could it be possible to make an oscillator circuit transplant?I tried that by removing the complete oscillator circuit of a 1972 AA5 Silvertone clock radio and rewire it into the 84B,and for the open primary of the antenna coil I reconnect the coupling capacitor to the secondary side,after realigment the radio came to full life and the customer was very happy.

Oh it's not too scary! On lot of the early Philcos the primary of the of the anttena coil and the feedback winding of the oscillator coil go open. The small cotton covered wire rots and you will see green spot in the winding. You can check it with an ohm meter all should measure a very low resistance like a few ohms. If not it's time to rewind!
