Ten years ago we sent out parts to be X-rayed irrespective of supplier.
So much paranoia...


But now i'm coming around and just maybe its the way to go.

Has anyone buit a 100% counterfit parts amp?

Notice any difference in tests?

I haven't built any amp entirely out of counterfeit parts, but I have "used up" a batch of fake C3281's in places where TIP3055's would do. They work fine at 50 or 60 volts.

Testing? None, other than it works and doesn't blow up.

Sounds like someone is a sucker for punishment!

Why on earth would you even attempt this? The entire point being the counterfeit parts have no standards. You probably couldn't build the same amplifier twice unless you bought a ton of parts. What would the parts list look like?

I think you are further ahead buying lottery tickets, and if you win you buy yourself an amplifier (but not before!).

Not knowingly! 🙂

I made a DOZ with fakes and the magic smoke emerged and I've bought a pile of fake jfets that I could bodgie something up with...

That said my time is short and I have enough real projects, so the best use I'll put the fake jfets to is as ccs's

Well I thought about it a lot and after visiting China, realized here in Texas we could not even make counterfeit parts.

I guess at some point the issue becomes blurred.


That is the point.

Hi Bruce,
I know where you're coming from. Sometimes when a committee chooses the "cheap" option, they discover the price far exceeds what they bargained for. Now the fab is long distance outside of the country, and they likely speak a different language. That is an arrangement for disaster. Oops!

Now these semiconductor companies need to regenerate their own fabs again, and generate a workforce with the needed skill sets. Sounds like fun to me.

When I worked at TI in Stafford, Tx. many years ago, TI was required by DOD to keep a minimal fab line in the US for wartime use. It worked out just fine because LSTTL was in high demand and no problem running three shifts.

They were also required to do a live run/spare parts batch too. Bit-slice ECL and TTL.

The little fab could also do engineering prototypes and debug tough production yield problems.

Lot of real world uses.



Maybe there is a fab deep in Cheyenne mountain but we'll never know.

So Cheers
Bruce
