Dumont RA-103D

[Phil Nelson]

The Dumont RA-103 is one of my favorite vintage TVs. Well engineered! Here are some restoration notes on my Meadowbrook:

That's an "original recipe" RA-103. Your RA-103D is in the Rumson cabinet:

I think the "D" model has a couple of different tubes & sundry other changes, but isn't radically unlike the RA-103. Download the Sams manual here:

As for weak spots, you won't find many. The focus pot is troublesome on some early DuMonts. The tuner mechanism is a little complicated, but the tuners are usually fine after you remove the old petrified grease and clean/relube everything. If the tuner feels stiff when you get your set, don't force it!
