think Vgs for mosfet based one , and think Vbe for bjt based one
there is nothing wrong in some reading , Greedy Boyz
Time is the thing wrong with reading. I don't have enough, can't remember from one year to the next anyway.
Trying to learn Linux for Raspberry PI. Greedy boy, wants it spoon fed.
Just want a good sounding reg/multiplier without learning how to design one. Asking questions, I do learn somethings, going to forget a year later if I don't need it again.
So, there you have it.
Rush
I think zenmod is getting sleepy 😀
kean K-multiplier have a led flashing on power up, to protect transistors
but it also results in completely noise free power on/off function
its really cool
would something similar be possible with Juma's multiplier ?

no need for that Tinitus
whatever -= cap multi is what it's name is saying - it's multiplying cap value ( connected to base/gate) by part's intrinsic amplifying factor ( beta/xconductance ratio) , so it's elegant ripple remover
it's not replacement for Jules ( so it's wise to have substantial capacity after , for harder loads ) but in cases where approx. 4V shave of PSU voltage (remember Ube or Ugs ? ) is welcome , putting one is clever thing
almost as when Mickey Mouse took 4 flies with one stroke 😉

How do you know that it already doesn't do that ?
It's a variant of standard MOSFET cap multiplier, known here since Zen3 article. It is slow-start by default because it takes time to charge the cap that polarizes the gate of the MOSFET. That amount of time (RC constant) is defined by the value of the said capacitor and the value of the resistor that connects the drain and the gate.
I'm sure that everyone here already knows that, but thinking seems to be even harder task than reading... 😀
Second version of this amp
Speaking of reading, there is a second version of this amp on the second page of the diyaudio.rs thread (and at least one modification described farther along in that thread). It takes a little imagination to read using Google translate. From what I can tell the second is more difficult to set up.

thanks, good info, softstart function is nice feature
nice to know how it works, and where to find it 🙂
no, I dont read/understand very well, sorry
unfortunately a handycap I have
but Im used to it
Hmmm... Nice ecxuse, but it won't get you off the hook, you'll have to come up with something more convincing ... 😀

Not at all. It just sounds a slightly more relaxed/warm/tolerant-to-bad-recordings. And it has a bit more gain.
could be just another of my usual crazy ideas 😀
but considering that size may not be the main cost of a board like this....would it be possible, and make sense to also put Juma's multiplier on it as well
or would it end in a much more expencive size category

because a bigger board might not be a lot more expencive
I thought if it could be made 'breakable', or to be hacked off, by sawing, or whatever
but may result in looking 'less nice'
maybe not so simple as I first imagined
or, a breakable board could also be a more cost effective way to get 4 of your regs, etc
if some only want 2, you can break them yourself before shipping
but I don't know the prices

Hi Juma
( + the bouZ )
!!!! HELP !!!
Can you tell me...
...what is the function of the 1uF cap with 1.5R resistor in series, on the PSU ?
Cheers.
Si.
PS
gettin' there...
...a few more bits like IRF's to buy...
...measuring, and fiddling with some wierd shaped heatsinks at present.
Some pics soon, I hope !
