Eimac Tetrode Tube Identification help.

Post by kc0ax »

Hello,

I recently purchased half a dozen 8122 Tetrode tubes in a "Lot" sale. Under close examination, All the tubes were either RCA's or Burles.
But... to my surprise....1 of them is an Eimac, Its ID markings are CDTA2236. Pics included.
All these tubes are Medical pulls, Can anyone help me ID what this tube is?

Thanks and 73's

That looks like a new one. No fingerstock marks.
