Thanks gents! I am sorry I missed out on the convention this year. I am definitely there next year. Old_TV_Nut's pics looked great. Sorry I missed it. I did get a nice 19AP4 for my DuMont RA-108 through Kamakiri (Tim). Mine takes a bit to come up into the green, but it gets there. I am sure it will produce an image, but wanted to grab a great testing one to be safe. I think I am almost ready to start on my DuMont RA-103 (Doghouse). Of my 7 sets, got 3 working pretty good now and one so-so (my Crosley 630 clone). Think it is a tuner/alignment issue (which I do not yet have the knowledge or equipment to do). I get crappy pic and FM radio mostly.
Not bad for never touching a soldering iron or reading a schematic a little over a year ago.
