Hi, Would anyone have data for the ABC1 tube with the british 7 pin base.

Hi,

it's hard to imagine, that the data for the ABC1_7pin may differ in any way to the normal ABC1, with exception of the base diagram.

The base diagram for the ABC1_7pin is most likely the same as for the Mullard TDD4, whereas the data for the TDD4 are close to the ABC1.

Regards, Jacob

Thanks.. I mainly wanted to base connections...  so the tip about it being similiar to the TDD4 may be useful..  I'll compare and see if I can work suitable settings for an AVO model CT160 tube tester.
