I have 3 of these Tung-Sol valves, ONLY 2 are in the original Tung-Sol boxes and also the outer Tung-Sol valve carrier (5 tubes) will be included with these.
The other tube is Tung-Sol and new (old stock) however it is in a GE box.
These are original from the 1940's
1x tube is physically in excellent condition
1x tube has very light corrosion to the base metal
1x tube has medium corrosion to the base metal
(See the photographs for more detail of this corrosion - but there is no way these effect the operation of the pentode's)
These are all new in box (old stock) valves
Variable Mu Pentode, intended for RF use and designed for battery operated devices (1.4V heater supply)
Condition exactly as described
Non-returnable product
