The 13E1 is a beautiful valve, it is a beam tetrode designed for DC control applications. The ratings are absolute maxima and based on producing stabilised HT rails, when operating as a series pass valve.
See also CV6045 for more details as to construction.
Inside the anode can be seen two separate cathode and grid structures, both connected in parallel within the envelope. Series pass service is very demanding for a valve and so generous cathode emission is important.
The wide glass tube envelope is 60 mm in diameter and, excluding the B7A base pins, is 125 mm tall.
Reference: Datasheet. Type 13E1 was first introduced in 1955.
