The Very Best Amplifier I Have Ever Heard!!!!

[quanghao]

You have no knowledge of electronics so your practice does not mean.

If you have knowledge of electronics,you did not draw like that(you say your circuit is right).😉

true or not? You know and I know, and things I actually make things such as layout,

I'm using all the same as the schematic I posted!

The capacity of a connection may not apply to you, but for me, I see it right

 

[hien.t.nguyen]

Please see the image, line I is fixed. I = I1 + I2, I1 I2 increases, the reduction should decrease the VCE.
VCE Q29 is inversely proportional to I2 so P = I2.75 = 4.66x75 = 349mW <625mW.

What do you think it??

Hix,it is in static conditions.

When NPN in bottom saturated,it not so.😀

A42-92 was tested, no matter what happens when using a long time.
please see the FZT857, 957 under My PCB

...

Used long time not damage,have not mean it is good.

If signal is full,NPN in bottom saturated(Vce #0v) is it will damage.

 

[AndrewT]

Designing any To2 device to dissipate a quiescent power of ~50% of Pmax (@Ta=25degC) is completely bonkers.

What will the Tc & Tj be when the amp is relatively cold?
How high will the internal temperature rise in use?
How high will the Tj rise in use?
How will the instantaneous dissipation vary with signal?
How high will Tj rise with signal and operating temperature?

VCE pnp#150V => Ipnp#0mA VCExI#4.66x75

Hi!

please see all my work! VAS Use MPSA42 and MPSA 92
thanks

 

[quanghao]

And more!
thanks

???
Ipnp = 4.66mA in any case because it is CCS.

You use low frequency (1-10Hz) of sine wave in put,out put conector load true(4 or 8 ohm)

Used Oscilloscope to see signal in C-NPN,the peak of this signal # (V-) => damage now.🙄

My layout.

I test in this case!

 

[trinhanhtu]

I=I1+I2 => I2=I-I1; I2max => I1min; I1min~0mA
I2max => Vce2min => Vce1max
I1min.Vce1max = I1min.150 < 4,66.150

 

[hien.t.nguyen]

I test in this case!

Have you got some pictures your test?
can you show here?

 

[quanghao]

ok!

 

[hien.t.nguyen]

ok!

I do not know your picture.

1. Where is sine wave machine?
2. How much frequency?
3. Where is osc machine?
4. Where is measurement (in circuit)?
5. Where is the line DC (V-) on Osc? not see in display?
6. Where is load true?

Have you guys any PCB's to sell now or maybe in the future?

Hi
Before your guys step into this , please register for forum vnav.vn and use google translation to view what happen there , and why ?

Hi All!

This is part of the power amplifier, a positive connection between the K1058 and J162 G, you can refer to this connection.

I wish you good advice on electronic Watches on how this connection, to the reasonable value!

Currently I am using the values ​​as circuit diagrams, please visit

Merry Christmas

Merry Christmas!


I wish you love with forgiveness and tolerance, this key will cause us to be closer to God. Christmas!
