Neutralization of a Philco 87
#8

Kirbyc

When you first tried it, you said the radio worked great. Then you said the trimmer was good, then you said you had to rewind three coils.

Why don't you make sure the coils are all OK and are exactly as they were before they went bad, including the tap location etc.
Then make sure you follow the actual procedure and not what you think the procedure is. Like what if instead of trying to achieve the minimum signal the maximum is being achieved.
Your trimmer not working is suspicious.

Check all the tubes.
Make sure the tube used for neutralizing the stages is what it says it should be. Same tube that is either a dud with all structure OK except the filament is open, or a good tube mounted in a transition socket with one filament pin disconnected.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
