Default Re: Help with some old TV tubes.

Rich thanks for the information, i have downloaded a 29 Meg file from worldradiohistory site so that goes a long way to plug a few holes in my information held on the PC.


I am about to try and power the heater on the COSSOR tube, it may be to air, so I will do a quick emission test.
