Majestic (Grigsby Grunow) 50/52
#18

I’m pretty much done with all the electronic work except I still need to replace the cloth covered line cord. In doing the alignment, the set started motor boating which would change with the slightest tap on the chassis. Tracked it down to a bad ground rivet on the IF amp socket. It affected how well the tube shield would stay grounded. With the bad ground the shield wasn’t working properly thus allowing for strange oscillations and motor boating. I will order some new cloth covered line cord and antique plug. All that’s really left now is to refinish the cabinet which is partially stripped but that needs to wait til spring to do outside. Then a new grille cloth!
