Majestic (Grigsby Grunow) 50/52
#20

Yes Aaran I replaced that 2mfd cap coming off the 80 with a Solen cap. It amazes me how there is no hum in this set with such low value caps as that 2 mfd and the 3 mfd that comes after the choke and the big speaker! As for all the steel they used on this chassis, it not only made it crazy heavy but also very difficult to trace things and work on. It’s the worst chassis I’ve ever worked on but it is a decent performer considering the age of the design!
