[Boatanchors] RCA WR50B

[Jim Wiley]

If the bulb fits in a socket and is about the size of a #47 (#44, #49, 
#1850, etc) lamp. it is a NE51.  If it is about 1/4" in diameter, and 
has a pointed bulb with wire leads (no socket), it is a NE2.  If it is 
about 1/2" in diameter, fits in a socket, and had "D" shaped electrodes, 
it is probably a NE-48.  All of these are designed for 120V service, 
connected directly across the line  while using a series resistor in the 
47k to 150K range.  Don't forget the resistor - the lamp will draw way 
too much current and likely explode if the resistor is omitted.  If it 
isn't one of these, let me know and I will look up some other 
possibilities.

> I picked up an RCA WR 50B signal generator which appears to be pretty nice.  The neon bulb in the front panel didn't light when the power was applied.  In looking at it internally i see that it has 99 v across it but one lead right at the glass envelope was broken.  It looks like a small xmas tree light.  No manual and i can't read any markings on it.  Anyone know what type neon-lamp it might be.  Tuning is noce and smooth anyway.  Haven't tried it to see what kind of signal it puts out but it also has a "sweep" capability as well.  Down in the lower right corner there is an RCA (why not) jack for external mod.  Small package.  Anyone have a manual for it also?
