Way more than what I needed but nicely packaged. I'm not familiar with all of the transistors, so Ill be checking data sheets but these are handy. Tired of breaking a kit part and waiting three weeks for a part. I got a week ago and the single replacement 7550A I ordered is still on the way.

No issue

I haven't tested any of the parts so I can't comment on "quality" or "correctness" of them. What I can say is, from physical inspection: Good: - All pins were straight and the same length. - All components are of "the same size", look, and feel (meaning they don't look like they were all from different mfrs) - They didn't look "used" (i.e. pins were not colored from corrosion or anything). I've heard of rebranding of IC's but not individual transistors, so likely they are new. Not a "bad", but probably nice to know: - Pins are not "super long" but are still long enough for bread boarding. - The data on each transistor is etched pretty lightly onto each one, not "painted/inked". It might be hard to go through if you dropped several on the floor and had to manually sort them. My eyes are bad but I can still make the numbers out if I try. - The plastic case they came in is actually pretty nice/sturdy BUT since all the compartments are open when you open the case, if you ever dropped this on the floor (or popped it open and spilled some) when it was open you would be hard pressed to put them all back in their little compartments. Similarly, if you grabbed one (with tweezers/needle nose pliers) and accidentally dropped it into the wrong bin, it would be hard to find, as they all look identical. When closed the parts cannot mix as the tolerance between the lid and compartment is very small ( very good!) My suggestion: If you're clumsy like me and have the time, it would be worthwhile to transfer all of these to a secondary storage location of your choice. Personally, I put all my small "straight pin" low voltage components into individual "coin envelopes", label them with a pen, and close them with a paperclip.

a great assortment and value of transistors, I do communications equipment repair and have found this very handy .

Good Quality Nicely packaged fast shipping will buy again. Use the proper temperature and heat sink the legs to avoid overheating these.
