CV15, low power version of the CV1090 micropup without the anode fins and with a bolt-down heatsink for conduction cooling instead.
Markings on the valve are 37K, P on one side of the block, and CV15 stamped on the other.
Cooling should be provided so that the temperature of the anode does not exceed 140C, even if just the filament volts are applied.
