Looks as if the PA20 is a replacement for the 2P although the filament current of the PA20 is 2A its only 0.7A for the 2P
The 2XP has a 2V 2A filament but has a higher Va then the PA20
Later versions of the PA20 had a higher Va making it a better match to replace a 2XP
The GM of the 2XP is 7 and VA 300V
Does the set have its back? most Cossor sets of this period have the valve line up and their location pasted onto the back.
Sadly your wrong about lack of demand for 2V triodes almost all Cossor sets of this period are now plundered for the triode.
Lots of these sets have a random valve in the socket or empty when offered for sale.
