Talk:7JP4

Please check electrical characteristics section for discrepancy.
There is a small but possibly confusing discrepancy in the 7JP4 Electical Characteristics section. I believe this should be cleared up for everyone's good.

The tube element naming is inconsistent between the text table and the hand drawn pinout image. - image: - The hand drawn pinout image lists pin 9 as G2 (grid 2). It should be called A2 (second anode / anode 2) to align it with the data sheets. CRT data sheets almost always refer to the focus and acceleration elements as 'Anodes' rather than 'grids'.

Additionally, in the referenced External Links Datasheet PDF file, the base diagram/pinout is not clear.

There is a free-to-use very clear base diagram in page 1 of the data sheet referenced below. It is already a JPG.

This data sheet also gives operating conditions for 4000V instead of 6000V on A2, which may or may not be of interest. — Preceding unsigned comment added by CRT Hobbyist (talk • contribs) 03:07, 8 April 2021 (UTC)
