The POVT201 is the UK GPO designation for the commercial EF36 receiver pentode.
Mullard specify this device as for general purpose voltage amplification and for use in phase inverters etc. This valve was obsolete by the 1960s, and our data sheets show that the EF36 had identical characteristics and pin connections to the EF37 and EF37A. These three variants were all high gain low current voltage amplifiers from Audio to HF.
The reverse has the serial number 71760. The red paint indicates a Mullard made valve.
The classic envelope is 30 mm in diameter and, excluding the IO base pins, is 84 mm tall.
