Revisiting some "old" ideas from 1970's - IPS, OPS

[mchambin]

Electron - Wikipedia "The invariant mass of an electron is approximately9.109×10−31 kilograms, or5.489×10−4 atomic mass units. " If you can give a better explanation in simple terms for someone new to the hobby feel free to pipe up, otherwise quit trolling.

I am not trolling.
Your re invention of science is plain non sense.
Your bogus science must be dumped to not polute new minds.
Quit your bogus science.

Hydraulic analogies, as well as some other pipe-based analogies, are widely used for explaining the key processes and dependencies in electronic circuits.
Just some examples:

mchambin,

Pourquoi ne vas-tu pas faire ce genre de commentaires désobligent ailleurs. A la place, tu pourrais donner un example, non? C'est vraiment désagréable lorsque ça arrive et c'est non-productif.

Merci de ta compréhension

I am perfectly aware of the electric hydraulic analogy and its limitations.
The analogy from a bozo scientist who said I am trolling is wrong. Oscillations in electric circuits have to do with L and C, self induction and charge storage, they have nothing to do with electron mass.

This "Bozo Scientist" is just repeating what was taught to me by two electronics teachers in high school and another in college. I have lots of respect for those teachers. So far I have little for you so your opinion of me matters little.

 

[Lazy Cat]

Electricity like anything else has mass.

Who teach you that?!

There's no such thing as electricity.

Electric current DOES NOT HAVE MASS and has nothing to do with fluids flow.

OMG there should be immediate administrator's intervention on such nonsense.

Dans la physique de l'électrostatique et de l’électromagnétisme, nulle part n'intervient la masse de l'électron.
Des coups de béliers en électricité.......C'est hallucinant !
Que l'on répande de telles bêtises est inacceptable. Qu'on raconte qu'un prof a pu enseigner de telles âneries m'est insupportable.

Lazy Cat is right: Electric current DOES NOT HAVE MASS and has nothing to do with fluids flow.

Guys, can we move to something else? Let's talk about the amplifier or anything that has to do with it, otherwise this thread will fill with OT subjects. Please kindly don't reply to this, I just want things to move forward in a positive direction.

My two cents

Pinnocchio and mchamblin, Please include an English translation with your posts if you are going to converse in French. This is an English language forum.

I'm happy to see multi-language posts, but the English must be included.

Just placed the transformer order at Toroidy but in the meantime, I have a 400VA, 32Vac dual secondaries transformer which should be able to give me close to 45Vdc after rectification. Would that be ok to make some tests?

Thanks
Do

 

[jwilhelm]

45V should be fine for initial testing.

 

[vzaichenko]

Yep

 

[evanc]

I should have some pics of finished amps by the end of this weekend. Putting the parts in a useable chassis takes me quite a bit of time

 

[AndrewT]

Evanc,
you have twisted most of the cables in the upper half of the left pic.
The lower half has green and red cables that appear to be NOT in pairs.
Can you identify the pairs of Flow and Return and twist them?

 

[pinnocchio]

Hi Evan,

Which input stage are you using in this build?

Ciao!

Hi Do,

This is NS-OPS. Output transistors are at the bottom of the board.

Cheers,
Valery

 

[pinnocchio]

Hi Valery,

Yes, I know it is the NS-OPS but just wanted to know which IPS he was using since you have several available.

Thanks
Do

 

[vzaichenko]

Ah - OK! My fault - I have read it as "output stage" ))

 

[evanc]

The ips is the vertical VFA. I’m using an older version of the 21st century protection set.

I have one amp wired and playing. I’ll hopefully get the second done this weekend.

Andrew. I’ll neaten up the wiring before I call the amps done. Even with the wires running all sloppy the amp is absolutely silent.

Thanks to Valery and Jeff for the great projects help and education.

Evan

Got the second channel running. I had trouble with the controller saying ac failure. Spent some time trying to work it out but I got frustrated and deleted the stop on ac failure line in the program. I have a couple more protection sets I’ll build up and sub in.

The amps need to play for a few hours to get final bias and clamp settings made and then I’ll plug them into my system for a real listen

Thanks again, Evan
