Must be below ~3v. Pin 3 varies but pin 4 is virtually always very near 0v when the amp is operating.
When you check them, does the probe to terminal configuration show the reading expected for each type?
I've seen mismarked parts so I have to ask.

It is 0.4ohms but thats my test leads ohmage but ok im going to clean everything up then going to put fresh transistors in then will check the voltages again
Sorry for waisting your time mr perry but the supplier gave me both pnp transistors thats why its not working
I used a lcr tester and it shows pnp when its supposed to be a npn thats how i found out and the codes dont match up on the surface mount transistor
You need to stop using that 'tester' and learn what your meter is telling you. The first time you tested the transistor with a multimeter it would have told you what the problem was. You are not alone. FAR too many people are relying on these cheap little testers and aren't learning to test with a multimeter.
I tried the multimeter first but the probes on my meter are to big to probe properly on these small chip transistors so it is a bit of a struggle for me thats why i tested with the lcr tester and thats how i found out its a pnp and not a npn
