Wow, thanks for all the help.
Right now, it's not a curtain burner. It has a conventional AC cord which is not original, but it is a cloth cord in excellent shape.
There is indeed a stand up resistor mounted between the tubes on the top deck. I haven't really looked into it but I'll see if it seems to be a factory installed resistor or added in.
I did an RCA curtain burner a few years ago and swapped in 8uf worth of film caps (plasma TV sustain boards are full of film caps of high value) and installed a conventional cord so that's an option here to remove the high wattage resistor.
Under the deck, it has several of the tubular paper caps paralleled with smaller value micromold caps that are not the typical square ones, but bullet shaped. They are cleanly installed and I can't tell if they're factory or not. Also, a couple of these same caps are in series with larger paper caps. I think a schematic would be really helpful on this one.
Also, I have heard of micromold resistors, but have never seen one. Are these bakelite molded cases like the capacitors, or are micromold resistors conventional in shape and markings?
Yes, it looks a lot like the model in jr_tech's post!
I'll take a picture of it when I get to work today and post it.
Thanks everyone.
John
EDIT: Looking at the link that jr sent, this looks a lot like it although the tube complement is a bit different. The picture does show a stand up resistor so the one in mine is probably factory installed - so maybe the heat barrier was also factory installed or at least replaced with that poorly fitted asbestos sheet along with the power cord years ago.
