Title: Tube ID Post by: DMOD on January 01, 2011, 12:41:42 PM While on vacation in Kansas last week I acquird a number of parts, two Boomerang's and a Western Electric tube with a ceramic four pin socket.
It appears to be a glass envelope Tetrode with four base pins and some type of weird plate cap: number on tube is 524417. I will most likely tear down the Boomerangs for the power transformers, coils, and caps. As for the tube, is it useful for any AM projects or should I use it as a display item?

From what you describe, it may be a ring modulator tube that acts as an electronic switch to pulse a magnetron radar tube.

However, there were probably hundreds of experimental, prototypes, or those that never made it beyond the prototype state, that were just assigned a "X" drawing code that consisted of 4, 5, or 6 digits. Sounds like you have shelf queen. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
