Q: I drop my iphone in a cup of tea and now wont turn on, how do i fix this

Are transistors still really used?

Snuck a reply in there didnt'ya, and I was stupid enough to answer, I don't pay attention like I did before my head went bang, but I will pay closer attention from now to ensure against any repetition.

And with that I am out of this thread (new posters excepted) talk about bridges.

They just have become smaller. They never went away.

Didn't realize that.  Can I safely believe that vacuum tubes (and gas tubes) are out?

I still use punch cards.

Some new high end audio amps actually use vacuum tubes. But it is a niche market.

Do you remember the ones with the round holes?

Wow.  I thought that I was kidding.

What about 110V relays for control circuits?

Who is "he"

I am terribly guilty of not using the fancy quote box thing.  I am responding to your skepticism about the interaction I had today with my 5c rear camera customer and his comments.  This is not a "story" but a near real-time accounting of events that happened as this discussion unfolded today.

A guy gets lied to Apple Store due to their incompetence or deception.  He gets quoted an outrageous price for "repair"   He comes to me, I fix his problem with "used" parts, i.e. swapping a rear cam from another 5c, the other choice would be a new camera that is indistinguishable from the one in the iPhone both in appearance, function and quality.   He pays $49.99 and leaves happy.

I can understand why it would seem "convenient" and therefore unbelievable, but the reality is---this happens ALL THE TIME.   And this is why it is so painful for the folks doing quality independent repair that care enough about the industry to put a few dozen hours here on this forum into showing the consumers what quality independent repair looks like-----and then to have you make flaming posts "do not trust independent repair"

You make me sad today Csound.   I've tried hard not to insult you or make light of your beliefs.  I can understand your skepticism.  I appreciate the time that you clearly put into the Apple Support Community.   You're entitled to your opinion of course, but it makes me sad that you would choose to go out of your way publicly today and denounce the craft that feeds our families and that our customers love.    What a mean thing to do.

Vacuum tubes have made a comeback. For high end audio they never went away (I still have a tube amp and tube preamp that are 50 years old). But they are being used in military electronics, because they are more resistant to HERF attacks.

I do, too. They make good bookmarks. Not so much for kindles, however.

You've got to at least tell me that gas tubes are out.

Unsure. Relay is a pretty generic term. i'm sure you can get a relay for any voltage.
