Fast shipping, chips look good. I will write an additional opinion if something does not work.
These PT2399 are not new. Solder on legs, legs are bent and cut.
They work well. I'm happy
Came on time I tested and it worked perfectly.
According to the tester, not all transistors are equal to HFE. Gebryik 5 transistors in a linear power supply for HAM tanseiver.
