In my opinion all DCG4/1000 variants have a filament voltage of 2,5 volts.

So the here stated 4 volts must be wrong.

I do not see (yet) a way to propose a change to the data of this tube.

I came upon this electron-tube because it looks to me as a replacement for the DQ2a or the 866A.

The DQ2a is part of my collection.

reference: P.H. Brans vademecum 17th ed., Philips pocketbook for hams 1962.

Best regards,

Jan Terranea.

Hello Jan,

I've changed the filament voltage to 2.5 volts, as this seems to be correct. Thank you for this useful information.

Best Regards, Jacob
