I got a test data of 2.5 EV8-3109 50 52 A 3 50 from an internet site.

Strangely my 2DF4 indicate full scale on my TV-7.

The range A is usually used to test rectifier tubes.

Does someone have experience testing 2DF4 on TV-7?

I could not find 2DF4 test data in my TV-7 test data book.

Thanks in advance.
