Hi, again, everyone:

I have another issue with my 604 that I'm wondering if anyone has addressed. The dial lights are awfully dim. In a brightly lit room it is very difficult to see the little slit light image on the back of the tuning dial. When I first turn on the set, they are really bright until the filaments get warmed up, so I am afraid to try a lower voltage light. The Philco parts list doesn't actually tell me the lamp type, so I picked a couple of 47s and put them in there. Is it possible I have the wrong lamp?

Also, the series resistor in the filament circuit gets really hot, like unpleasant to put my finger on the back side of the chassis. Is this normal? I have a variac on it, running at the rated 115 v.

Again, Thanks!

Mike
