Hi Ron , Poston and All ...

Had a little problem . Everything was working great .
Only had to roll trimmers back and forth and basically
put them back where they started. Got the M4 phono changer
to drop records, amazing ! Then hooked in a modern turntable
directly to the banana jack on input side of phono transformer .
And that worked (mono)!I am going for more original changer but
was curious. I was ready to put the chassis back in and call
it done. Switched back to AM nothing ! FM , Short wave ,PB no
stations .Tap antenna lead with screw driver got a pop type noise.
Put phono back it worked. Shutdown looked carefully at wiring. I
have forgotten to solder things before.Found white wire from terminal
board to band switch tinned and wrapped around lug but not soldered .
A place I did not work on ! That wire was must have been fine until
I moved the other end of it putting in caps. Actually the person that
did that made a great mechanical connection that lasted until I moved
the wire. Anyway everything works again .I aligned the set by ear.
AM and short wave are better than any older 41-42 models I have (or as good).
FM sounds excellent! Very happy with that ! I had to redo the Am alignment and FM by ear again. Tried to do alignment with meter/scope/signal generator but could not get it to work.To late at night to continue .So I did it by ear.Now I recall that if using a VTVM and not an output meter you have to get on the AVC line.I Kind of remember the last one I did I swore that I would make a loctal adapter for this .Never did though. Even though the Fm sounds great I am not sure it is best it can be. Put Cap wire back as prescribed. Seemed to work equal both ways. But as I said do not think it is 100% yet. Seems to be a lack of FM channels on low end of dial.sound quality is there .So I am leaning toward full alginment with meter .May need help on this alignment . Never did FM . What is special about the "output audio meter " that a VTVM can't be used on terminal 3 to chassis ? Or am I wrong in recalling this ?


To recap on the wire and capacitor and be clear about what I found. I would have to say it did not matter. The leads are in a wide open area of the chassis where there is little for high freq to jump to or interfere with .
Even so I go with the recommended repair.That is because I felt under certian reception conditions it could matter . Plus it is a neater way to wire.
The general rule I follow is do not move these type of wires or change thier lead length. I think you can adjust out lead length to some extend .But if you place wire in wrong area it may cause problem that can't be adjusted out.Once this is done I am not going back in to move a wire .

Therefore I go with the way it is on Ron's site.

Thanks for all the interest and help ... Bill !
