Maybe the P2 page contains some mistakes?

Hi all,

According the Google search, the P2 is a vacuum triode. Filament is 2V 0.2A.

I'm not sure about the base, maybe there is UY base version, but I saw only europa 4 pin base version. 

I just bought one, it also has europa 4 pin base, and works well with the above filament setting. 

I'm I right?

Where to upload it's pictures?

Otto

Hi Otto,

there are various versions of a type P2 tube from different makers.

Your picture clearly shows a Marconi version, hence it belongs to the page P2_Marconi-Osram .

Best Regards,
Jacob

Hi Jacob,

Thank You. 

The shape is like tube_p2_commontype.html

Which one is the right place?

Best regards,

Otto

Hi Otto,

Since the brand is clearly visible, your pictures should uploaded to the page P2_Marconi-Osram .

The page P2_Commontype is rather intended for tubes without a visible manufacturer's brand.

Best Regards,
Jacob
