I purchased 50 that I have no need for right now but what the H*ll

It looks like those are used LM3886 devices:

LM3886TF audio amp. TO-220,11 staggered leads, isolated package. One of the best audio ICs around. Check out the specs at www.bgmicro.com then go to "Data". We carefully removed these ICs from the circuit board and now we offer the savings to you. Just like all of our products, they are completely guaranteed.

But, I guess if they are guaranteed to work, that is fine. I would rather use new devices myself, even though they are almost twice the price as this.

These heatsinks do look nice:

a few of them arrived today... some heatsink compound on them and the cut the tips off to make desoldering easier. pic of new chip from digikey aside the 1.99 removed chip.

I would also suggest changing trow after working out. Buying used semiconductor devices is akin to buying used latex protection devices.

What could possibly go wrong?

I don't believe in used parts for a final design. The leads look a tad short to me and maybe unusable in a PC board. I would pay full price for new parts.

[HIPCHECK]

they also have these heatsinks,

this might be helpful to some class A/SS amps

You could forget to put it on.

Are you referring to the previous used latex devices comment, or the used semiconductor devices?



Anyway, the heat sinks from BG Micro seem decent, but I still don't support buying used semiconductor devices.
