Anyone have specs for a 2033 dual triode? It has a 7 pin base and a common cathode like a 6J6 but different plate structure.

A search of Usenet found this:

The 2033 was purchased from RCA by Remington-Rand and
Minneapolis-Honeywell for computer use. It is essentially a 6J6 with the heater current cut to 0.3A and improved plate current characteristics.

The one specimen I have tested good as a 6J6. Incidently, I have a few Mullard 6J6s that look like this, with separate cathodes.
