Are you still online? Check the circuit diagram. Some friends said that my test was

I think you did well....!

Thank you, now you can form pairs for us!

And I see you use a DMM now for the gate voltage.

pardonnez moi mon ami, i don't think mesuring at a VDS of 9V is correct for the
ZM amp , i thought it would be 19V VDS at 1.8A ..

but please use an heatsink or a piece of thick metal under your VFET

Are you still online?

Check the circuit diagram. Some friends said that my test was wrong. The above comment is from BBS friends

Please help me to see if I made a mistake

 

[juanitox]

if you use 19V Voltage drain to source at 2amp the Vfet will run at 38W so you need an heatsink !!

 

[generg]

The battery is 9V, but the voltage can only be 9V. The drawing information I saw looks like this, I don't know if it is correct

Can you please tell what voltage you have at the drains? I did not see it on the pictures.

Hello, this is supposed to be a 2A to 9V grid

Not 19 v 2 a

The radiator will be on tomorrow. I forgot to bring it to work today

What do you mean? I don't understand
Voltage? Are you talking about a door? VGS?

Your power supply delivers 24 or 20V to the SIT drain?

And Pras1170, it is so good to have you on board!

 

[pras1170]

Your power supply delivers 24 or 20V to the SIT drain?

You mean: power in the picture, right?

Yes, 24V power, right on the right-hand side of the picture, right?

 

[pras1170]

9 v battery
24 v power supply
Set to 9V, 1.8a and 2A and use 24V power

 

[juanitox]

1 : use a heatsink or a big piece of alluminium under your TH51
2: set your 24V power supply to 19V
3 : adjust your 9V bias supply to get 2A and you get your voltage bias rate (normally between 2 and 4V)

4: take a deep breath and Wait for ZM return

just amateur comment:
guess 24 Volts is ok cause it´s estimatet for final use (classic FW numbers)
take care of "-" minus, Vgs is negative,

best

YES 24V
Why did a friend ask me to switch to 19V, I really don't understand, my power supply is 24V

Am I doing the right thing?

 

[Ben Mah]

Yes, nothing wrong with 24V. In post #81, Zen Mod recommended 19 to 25V.

 

[pras1170]

Yes, nothing wrong with 24V. In post #81, Zen Mod recommended 19 to 25V.

So I don't need to do 19V power, it's enough for me to get to 24V

So I have measured several new values, and they are written on the back. Is that right?

meet the requirements of ZM ？

 

[Ben Mah]

24V is good, no need to measure at 19V.

 

[pras1170]

Am I right?
How much difference does this number match, how much and how much can the value match?
(error value)

Hello Pras. Your measurements look good. I received the Tokin devices that I bought from you and will measure them this weekend too.

How hot was case of the THF51s after you measured them? (could you still pick them up?)

.. dB

What is your username on ebay?

I don't know who you are, thank you

I don't want him to work too long. I look at the Numbers and turn off the power

(when you want to change another one, you need to take it off. I'm afraid to take it, but you can try to take it to the side and move it to the side.)

The hand is actually very afraid of being scalded（The hand is actually very afraid of being scalded

Why waiting, he does a good job!

I put on the radiator
The picture below is a heat-dissipating test (the result of placing the heat-dissipating aluminum sheet)

Look (I don't have time to measure that much, these THF-51S are still those tested yesterday)
So I measured a few THF-51S that I tested yesterday (I want to re-measure the difference in the case of heat dissipation without heat dissipation)

The picture below is still yesterday's THF-51S

The result of the heat dissipation process, please see
