Electronic – Is it possible that a new transistor is not good even if a current runs through it

repairtransistors

I just got an NTE121 replacement transistor for an old 2N2148 that was in a guitar amp. It was the only part I replaced and now I have no sound coming from the speaker. I checked every component on the board with a multimeter and did not find any dead spots, including the new transistor. Is it possible that a new transistor could be dead out of the box? I have really only ever dealt with capacitors before.

Thanks

Another transistor in the signal chain was causing the loss of signal..
