New Penta Amperex 3-500zg Lit Up And Producing Power In A Drake L4b On 20 Meters First On Youtube

Here I show the rated output of drake l4b with the new Penta Amperex 3-500zg Tubes

I start at 4:15 , sorry for repeating myself about the cutoff resistors and meant to say penta tubes installed not reinstalled

Long day

Enjoy
