The transformer (in the above diagram) can be a 220 to 6V or better (I think) and tube amplifier output transformer.
In this case voltage is not most important, it is current that you are trying to influence (it is a shunt PSU) and the most common signal generators are equipped to generate voltage (mostly into a 600 ohm output impedance). That is where a high ratio transformer will be helpful.
And no, I am not going to invest time in selecting transformer(s) for this purpose, if you are planning to do these measurement experiments then I would say go ahead and start by using the suggested transformers, and then from building experience you will grow to knowledge needed, and then may select different devices.
okkk okkk.....calmmm down...let's keep tone naturally flowing please!
You don't have to invest anything geezzzz!!!
You mentioned something very generic that I liked you to support your general statement with an actual reference for anybody's benefit.
You don't have to do anything don't worry! 😱
😎
Ohhh no, it was not intended to be 'harsh' 🙂 sorry for that
I think the first part is the important one.

ahahahahah!!! That makes me feel better!!!
Yeah the first concept is very important.
Like you mentioned I will have to get a transformer like you were suggesting and try out see how it works and then like with any other things improve the set up as you are getting more proficient at it.
I am very glad you posted the last thing! Thanks.

check what Walt Jung did for PSU testing, its kind of a refeerence in this field (should be on his website, sorry the link escapes me right now)
My pleasure.
Just keep in mind that it's always the circuit that primarily defines the sound quality, not a single component (type).
If it sounds good, praise the three musketeers, instead of licking capacitor leads.
Oops, did I mention that I acquired the very last of the PCB packages for the Locky curver tracer.
For which I already have a fancy all-aluminum housing, bought a bunch of them for €5 the piece (>100 new)

Makes both you a happy camper, and me.

I know it will sound good.... it is the sum of the parts....
PS: I never lick the parts leads, I normally polish them 🙂

Now I do not understand 🙂 spit and polish - definition of spit and polish by the Free Online Dictionary, Thesaurus and Encyclopedia. 🙄
Spit, lick, what is the difference?
Some do.
(PS: I own a Philips PM6507 curve tracer, with all accessories + SM. Does Bipolar/JFET/MOSFET, up to 20A Ic and Gozanga Vce. Once every couple of decades, universities have a clearance sale, bum students are the first in-line to profit. Plus an Hitachi digital storage scope with RS232 output & software. But it's always nice to keep up with the modern day and age.

woo that's cool.
So you are gona rig up his curve tracer too? Nice!!
I still have to order one.
I am not as brave as you.....getting too lazy lately....going to get finished unit one of these days.
As I said, go and get one 🙂
Alternatively, if still not convinced, bring a nice bottle, and you may try mine 🙂
Populated PCB/calibrated/software CD, same deal as Frans and all the others got, merely needs a heatsink, PS and a case.
Brave is cleaning up the board, swapping components, recalibration.
For a couple of the parts, I've got the better versions (which no one else has
) Still, could be simpler than working on a submarine, or building cars, yachts, jet fighter sections, commercial airplane parts, repairing a b&w TV with tubes, or the high voltage section of a 42'' LCD. Me pathetic d-all-y.
(I do turn extremely agressive from programming, had to do DOS/Fortran/T-Pascal/Visual at university, smashed a lot of stuff in those days. A parttime job as a Unix system administrator was easier)

ahahaahahahah!!!!!!
I quite liked Pascal....however hated Fortran....which they forced us to study in university for one class....and I haven't seen anything in Fortran since then!!!!!
