For sale a VP41 (AC/VP2 / MVSPenB / W42 equivalent) RF variable mu pentode amplifier valve / vacuum tube by Mazda, on a Mazda Octal base. This is NOT THE SAME as the standard International Octal base. Fully tested at 100% of nominal new emission no faults.
The VP41 is a four volt parallel heater valve and was extensively used in pre- and wartime mains table radio receivers as the gain controlled IF amplifier. Four volt "mains" valves were developed prior to the American standard 6.3 volts valve was introduced to the UK, as in houses without mains electricity they could alternatively be powered by two standard 2 volt accumulators wired in series.
This lovely old valve is very slightly used and still tests 100% on my Mullard High Speed Valve Tester. In good clean condition for age with all original markings fully present and readable (see picture).
A sensible price for fully working, usable example of an interesting and now historic old device. Ideal for vintage radio set restorers and collectors alike.
