Default ARP12 and AR8 valves

I've had these valves for years and always considered them to be some useless ex-mil types. I'd never find a use for them.

However, I checked out the details of them and in fact they'll be of use someday.
The AR8 is a 2volt double-diode triode and is similar to the Mazda HL23DD.
the ARP12 is a 2volt vari-mu pentode and is similar to the Mazda VP23.
Both have the Mazda Octal base.

The ARP12 has a Mullard look about it. The date or production code on the base is definitely Mullard style. A valve with a Mazda Octal base made by Mullard.
