Hi All,

I have an OS66 tube. I haven't found about it anything in rmorg. Even the Google has only one hit in a hungarian page. According this page it's a Tungsram replacement of the ГМИ-83. The parameters are similar, but slightly different. I haven't found any other data. Based on the informaton above I made some measurements. I found the base and the base connectons are the same. Using 25V heater voltage it consumes 1,44A currrent. Using Va=400V, Vg2=150V Vg1=-5V the Ia was152,4mA.

Does anybody have any other information?

Best regards,

Ottó

Good evening Ottó,

unfortunately I also didn't find any information about this tube, but at least we have introduced a tube page for it.

Best Regards,
Jacob

Hi Jacob,

Solved. 

Mr. Lászó Fogl sent me an old digitalized Tungram catalogue, which contains it's data and pinout.

Best regards,

Ottó
