A few basic questions about tweaking, components

[phsyconoodler]

Again,not true.Show me one PC board that has a solid mechanical connection.all have components inserted through eyelets and wave soldered or hand soldered.No wrapping,no mechanical connections of any kind.
Pretty much the basis of all modern electronics.

Not true!?

Are we talking about amplifiers made the old school way or a VCR made last week?

By your reasoning show me one amplifier with a turret or eyelet board that has been wave soldered!


One pic? How about two?

Clearly these amplifiers are using mechanical connections throughout.
The Peavey is unquestionably using mechanical connections AND is wave soldered.

I suppose I could post gut shots of a VCR if I haven't already made my case.

Tweak soldering eyelets, here's what I do - If an eyelet has 2 or 3 leads in it interlock the straight tweak leads into the tucked under non tweak leads, if it has 4 or more leads in it just getting it in the hole is mechanically enough. Tweak soldering turrets - I wrap the components on the post and only use the hole for wires (ususally from below board).
And horror of horrors I've sometimes just put the straight lead into the eyelet and soldered it. If you use good solder and good board material I can't see how it would ever become an intermittant.

Nothing like a good argument Christmas eve!
Old school meets new school.Old school is very sound and new school is frowned upon.
There are lots of PC boards out there that are very reliable from vibration and stresses and don't bend their components like Univox and Peavey did.Those little bends are hardly a solid mechanical connection anyway.Do you think maybe they just did that to keep the components from vibrating off before they reached the wave soldering tank?
We are splitting hairs here anyway.We both wrap components and we both like to do good work.The anal approach of wrapping a connection around a tube socket lug three times doesn't do much.Maybe stress the wire from bending it so much.
I have repaired many an amp that had incredibly good wrap on components especially at the tube sockets and they still had problems because the builder relied too heavily on that solid connection and did a poor solder joint.
I can solder the joint and lift the entire chassis off the ground,transformers and all and the solder joint is not damaged.Can't say that about the wire however.Three wraps don't make it any stronger than the guage of the wire beyond the joint.Just a pain to remove and diagnose.

No argument. Debate perhaps but no argument.
Sorry if I come across that way, not my intention.

The bends are indeed creating a mechanical connection. Check the .pdf I posted it's in there I swear. I certainly am not going to argue with NASA.
This is rocket science after all...

Indeed probably splitting hairs. Although I consider myself anal and not redundant. I never said anything about wrapping three times around anything much less a tube socket. That's not anal that's just shoddy.

I have repaired many an amp that had incredibly good wrap on components especially at the tube sockets and they still had problems because the builder relied too heavily on that solid connection and did a poor solder joint.

Well precisely and I can attest to numerous cases of a solid core wire essentially resting in a blob of solder in a tube socket pin because there was exactly no attention paid to the mechanical jointing. Thus why I said I feel they are two things that go together like pb&j.

I can solder the joint and lift the entire chassis off the ground,transformers and all and the solder joint is not damaged.

Safe to say it would be stressed and compromised in integrity.

Three wraps don't make it any stronger than the guage of the wire beyond the joint.Just a pain to remove and diagnose.

Again I never mentioned wrapping anything in quite that extreme. Mr. D did use a mechanical connection at the tube sockets. Wrapped around once and that is pretty much what I am talking about here.

Was it Zappa who said "If you shake three times your playing with it" ?

Anyway none of this was meant to be offensive to anyone, nor argumentative. There is no timbre' with the internet. What is meant as levity can be seen as otherwise... Sorry if such was the case with my posts and words.

No more amps today. Now I get to build a bike, a pinball machine, wrap some legos, build a lego set, stuff stockings, eat cookies, find the msising wrapped gifts that have been in hiding...... No dang elves to lend a hand either....

Merry hoho!

a good solder sucker is worth it's weight in plastic.

Hey,an argument is fancy name for a debate.
Nobody is taking offense.It's all informative anyway,whether we agree or not.Sticking to what you believe is not a bad thing at all.
I remember being on a debate team in high school and I was on the team arguing against extra-terrestrial life.I personally believe in it but was on the other side this time.We defended it successfully even if I didn't believe it.
And I don't care to argue with Nasa about anything.They went to the moon in 1969 with very antiquated equipment.I bet all their joints were wrapped!
Merry Christmas and God Bless us,everyone!

I thought you guys were talking about soldering
