I have Dale RN60 499Ω & Shinkoh 500Ω 🙂

 

[Salas]

Any other position where increase the SQ changing to a better component?

Output cap

 

[merlin el mago]

Zobel 10uF? What's the minimum value?

 

[Salas]

4.7uF

 

[merlin el mago]

Yessss, mine favourite Auricaps🙂

Tomorrow I will do mine homeworks!

 

[merlin el mago]

It's needed to change the value of zobel resistor if 4.7uF used?

 

[Salas]

No, its just a well working range 4.7uF-10uF with that same resistor.

 

[merlin el mago]

Ok Thanks.

 

[merlin el mago]

Finally used 220uF BG for Vref 4.7uF Auricap for Zobel and the trick for fixed resistor don't go ahead & left the 1K trimmer.

SQ 1st class highly recommended.

Salas can be enough 2200uF for C105 if set for 1,2A?

 

[merlin el mago]

There is 10.000uF in the separate PSU box.

Yes because in this case its role is more of a local decoupling capacitor

 

[merlin el mago]

Thanks.

Salas I have old regs. with only 3 Led's D1,2 & 3. Can be these old regs. don't reach 1.2A?

 

[Salas]

They will reach but with lower value Rset than later boards. Use green for the three Leds.

 

[merlin el mago]

OK I will try & let you know, thank you.

The board have yellow Leds.

Salas green I have 2 leds 2.1V 25mA & a lot of 2V 20mA?

 

[Salas]

Use the 2V Leds

 

[merlin el mago]

OK thanks again.

 

[merlin el mago]

Salas don't reach the 1.2A, with 0.1R 890mA loaded with a dummy load of 5R 40W, voltage across dummy load max. 4.5V

Vref 2 red leds + 1k trimmer 220uF lytic

Reg. Vin 11.11V

Tx unloaded 11.8V 3A

Wait Salas for more than 5Vout Q106-306 must be mosfet & I have installed BJT, I will change according manual, sorry for the inconveniences.
