interesting??? velly intillestingk!!!!! who said that? colonel klink????-or laugh in -well anyway r5 could be a resistor-but that is a vague description of its ailments -it may need a lot  more than that- does this have rca jacks/jack -has it been updated- if the capacitors are original do not plug it in--it will not last long if you do--that is a cool idea for small room or tabletop sound--gives me ideas--give us more info--are able to work on this thing????

dgb-F3 is a ballast tube--i had to search--essentially a resistor in a glass or metal tube with a octal base--i can see your confusion-as i was very confused looking at the pics in your first post showing all the tube bases from underneath--the following link is said to be a schematic-hand drawn-it may be the multiple resisitors on the left of schematic-not sure-pilot light would be a clue--seems to be several wires coming from the pins-turn it over and have a look see if that is so--
if you can't find one-you can simulate under the chassis easily enough-just not sure of the wattage

A quick look shows that there are equivalent tubes with double-voltage heaters - 50L6, 50Y6, ans 12SL7. Wouldn't that eliminate the need for a large ballast? Throw in a 150mA/6.3v pilot light and you are at 118.3 volts, close enough to 120v. Just a thought.

Here is the schematic for the Western Electric 100f Amplifier:

Look in the TCI Library for BSP 024-101-100, Issue 1.

thanks for the link "oldcrank",
i thought this thread was long dead.
i did redo a stereo pair for my flac player.
fun to think of something 60odd years old being
repurposed for high tech.
