I suspect that one of my coils has short in the winding.It is the secondary RF transformer coil going to the control grid of the RF tube.To get correct alignment, I have to completely unscrew the tuner's compensator adjustment nut, set it aside and bend out the upper copper plate (just totally delete the said compensator). At that point the VTVM shows the peak, but I hate the look of it without that nut and the plate hanging in the air like that.
So, it might be the coil. Both coils show continuity, one coil shows resistance, another is not, however it looks like it has very low winding count.
Should I just go ahead and rewind both of them or is there some other way to
verify?
Thanks.
