I’ve got the Atlas DCA55 to test transistors, I’m not too impressed with it, not for the price. It’s not terribly expensive but it’s not cheap either. I’ve found it to be a huge liar, maybe I got a dud, I don’t know, maybe I just don’t know how to use it either. Recently, testing the first IF amp in a receiver, this thing shows the transistor as being good. The part is a 2SC1674 but the receive is very weak, basically not even there. Lifting the collector, you can faintly hear the tone being injected. So at this point, I hunt for another possible cause, something that has to be wrong to pull that collector down. But there’s nothing wrong except this one part, the 2SC1674. Hunting for one in the parts bin, changing it out, presto!! The receive comes back to life. It also works with a 2SC945 in place or a 2SC1675. I have plenty of 945’s and 1674’s that I bought from Mouser but they are absolute turds and worthless. Every 1674 I put in, useless, no more receive than the bad part. Same thing for the 945 part. Lesson learned for buying those from Mouser. So my question, if you’ve stuck around through all that jibber jabber, is there a better tester that is affordable? Or, am I using the thing wrong or overlooking the numbers it’s giving me?
