Tubes have been tested by L3-3 tester.
I received these tubes in a factory sealed box. However, during testing, they showed parameters lower than those indicated in the datasheet. For this reason, these tubes are sold like used.
The price is for two tubes.
Please select tubes from the list and write to me.
