Victoreen was a manufacturer of radiation measuring equipment such as dosimeters, geiger counters and related apparatus. A corotron is a gas filled shunt regulator for high voltage. Not useful for audio in any way. They often contained small quantities of radio active materials to aid in regulation.

Thanks for the info, it's just happened that it was included in my parts haul and don't know nothing about it. If it can't be used for Audio, then it might be good for the museum or collection display.
By there looks i think they are HV applications by the term Corotron which mostly used before in our Photocopiers, Corotron wires AND CORONA discharge of KVolts range..

Raytheon CK5889 Electrometer Tube
While on the subject, may as well know. Before SS devices were available electrometer tubes were common in the research lab & radiation studies & measurement. They are primarily an impedance matching device from an extremely high impedance to something more in line with ordinary measurements. And operated at low voltage in order to minimize any ionic currents.
Measure extremely small currents, extreme resistances, Etc.
Some experimenters have used tubes such as the 6J7GT as electrometers when the requirements of the application are not as extreme.

Catshot here, going through my old stuff I also found the Victoreen M42C-9KV voltage regulator tube. Same question, does anyone have a datasheet for this tube? BTW, I have an old FSN database, 2GB worth from 1993. Yeah, a little old but priceless when looking up 'old stuff'. Give me a Part # or FSN and I'll give it a shot and send you the results in pdf.
