This tube is one half ECC83 and one half ECC82

A tube with two different systems inside, requires normally two cards, because settings are not the same and good / Bad limits are another too.

It would be possible to make such a dual card set for ECC832, but this is not needed, because just normal cards like for ECC83 and ECC82 can be used for the same purpose.

To test ECC82 part, use ECC82 card, and plug in only plug A2, and leave A1 open.
