this edited version tells the opposite story.salas said:every time I substituted such a ceramic by a fast PP cap, it sounded less edgy.
PP less edgy than ceramic.
The earlier unedited version has a PP substituted by a ceramic and thus gives the impression that the ceramic is less edgy.
Is this something to do with English sentence structure?
Sometimes I write fast and my native language is Greek. So please kindly pardon some of my linguistic mistakes. English I have learned in school as a foreign language, and I try to write as good as I can in forums, but not always successfully so.🙄

is wonderful cheap caps ,are 1% you can use on riaa ,as bypass to outcaps ,on speakers,as shunt the b+ to gnd 😉

I am on a good road with ''Valve Itch'' practical tests too. I will post in tubes forum when I am done.🙂

Yes Manu, excellent suggestion.

HI Salas , Andrew do not know my maccheroni English 😀 😀
HI Andrew
Hi Salas,
no need to apologise.
We can see you're from Greece.
Changing just one word has changed the meaning of the sentence.
I just needed clarification in case you really meant the first unedited version.

Yes, its so easy to blunder if not thinking twice when using a foreign language. That is why courts assign official translators when non natives are trialed, some times even if living in the very country for decades long.

Come on now! Why you say so?

Statistical question for all
Now that I am about to do the schematic resumes, I wonder. What is the mean average IDSS of the BL parts that you have in your inventory? The latest I got from Spencer are bunching rather high for instance. Shall I adjust values during the schematics standard making process too?

Hi Salas
What about using a polystyrene ? I have hundreds of those 4700pF (noob´s initial attempts into ebayhigifi)
Do jftes like heat ? (Like valves?)salas said:
I like hot JFETS too.![]()
The obbligato caps are beginning to show their capacities... Inittialy very closed, now quite spacy and with tendency to open.
I was thinking about bypassing them but now I will wait and see... Maybe the teflon in C1 will give me the needed extension in highs and lows, so I will not need to bypass the output.
(But I will loose the mid freq magic of the C1 PIO ?!) (Can I bypass the PIO with the FT-3 ?)
Based on your previous comments I understand my riaa is extremely psu dependent, it is also very transparent and reactive to every mod I do. (I am glad I have a super reg now... the difference is awesome...)
Now I can precisely set VTA and down force by hear. 😉
Ricardo
PS
I am building a shielded cable for the output lines, using inner stranded silver cable with teflon coat and the shield comes from a long run of high flex, double shield, marine grade ofc cable.
Of course i will only connect the shiled on one side so it will not conduce signal.
Don't know if it's helpful, but out of the 100 pieces I got, very few were in the 6-7mA range, and very few above 11mA. Most were spread across 7, 8, 9, and 10mA.
I'm curious, do you use a simulator to come up with different part values for different idss, or do you do it on paper/calculator?

Any good film cap wil do for RF cap.
Your final interstage and output capacitor mix with or no bypass depends to your taste, system, rest of components and cabling. I see that you are very expert in voicing. Since we helped you to go fast in the ballpark, now play ball libero.😉

Mean 8,6 (Same median)

I change the Beta data on the simulator's model. I have checked with practical circuit and it ties well. So given your parts, 8.5mA IDSS seems valid. Waiting to hear from more.
Re: Re: Statistical question for all
Aha! 8.5 was not a bad guess for now. Thanx. Lets wait for more answers.
