6P15P and 6P14P - what is difference?

[Guest]

People believe that 6P15P has weak 2'nd grid, while I believe that different specs are given for different guarranteed results because 6P14P (clone of EL84) was sold for audio, 6P15P was sold for linear video amplifiers.

What do you think?

6P14P is a clone of EL84, 6P15P is kind of a "different" tube with "better linearity for video applications", but I suspect they are the same except 3'rd grid pin in 6p15p instead of connected 3'rd grid to the cathode like in EL84.

No, it's about specs. Despite of differences in specs curve tracer shows the same pictures.

Thank you anyway!

Most probably I'll wait till I have both broken to see what is inside... But looking at photos I can't see differences between 2'nd grids, though holes in anodes are too small to see clearly.
