Reflektor-D builds

[merlin el mago]

You do a great work

 

[Salas]

How higher DCin you gained by excluding a prior C-mult?

 

[merlin el mago]

Now I'm listening Chie Ayado, tomorrow I will measure and let you know.

 

[Salas]

I am only asking bcs you run big current and more DCin can add heat. But you are still listening so it surely did not break.

 

[merlin el mago]

I can touch the heat sink, are only warm.

 

[merlin el mago]

R-D with k-m sounds bigger but seems to lose punch, can be R-D needs more current or more voltage in?

 

[Salas]

I don't know, very system specific and subjective what you tune. Try with some more Vin to K-mult or with some more R-D current solo sometime to see if you can combine best subjective traits. But always watch sinks temp.

 

[merlin el mago]

I will do tomorrow & rapport.

 

[merlin el mago]

1.87V

 

[merlin el mago]

BIII DCin measures 5.235V with KM and R-D.

 

[merlin el mago]

BIII DCin measures 5.205V only with R-D.

 

[CeeVee]

BIII DCin measures 5.235V with KM and R-D.

? are you talking about the Keantoken K multiplier before Reflektor D ?

 

[merlin el mago]

No, I reffering the Salas KM (attached schematic).

 

[CeeVee]

TKS

 

[merlin el mago]

The Salas KM is very useful with BiB.

 

[Salas]

*It has no special name. Its just a second order capacitance multiplier. KM is Keantoken's multiplier.

Very easy to assemble. I use it for 3.6V (red led + diode) and it's right on spot right away.
My current requirement is very low, 30mA, and now I've got 0.710/2=355mA CCS, should I aim for lower figure ? Heatsink is hot but no damn hot.

Somehow managed to miss that ...was only aware of the work by Keantoken.

Some years ago had a blast getting into diy with my budy ( if i may ?....) master ZM , by building a all new IV for a Shanling CD player (well documented elsewhere in the forum ).
It has been amazing ever since ......but methinks that a redone power supply is in order.
I really like the sound of the IV that ZM tweaked for me but the cap multiplier i made at the time was at best rudimentary....it was my first effort after all.

It seems i will try one of my (....errrrr your ) BIBs with your cap multiplier and go on from there.

Sorry for the OT.

No reason for less. Excess is good (in shunt regs).

So,
power to the shunts
and not to the caps
(i.e. cm circuit)
