so , just to name all DiyAs involved in this funny project :

Papa
AR2
Humble ZM
Leonardo
(as known on Baby DiyA)

:cheers:

What nicer than being around such a great guys like Mr.Pass and Dr.Choky?
I wish, next time, Nelson joins me as well. Wouldn't that be great? I loved driving from Belgrade to ancient Bach where Choky lives, and I know Mr. Pass would enjoy the scenery as well. Here is the picture of ancient Choky from my visit to Bach. Uuuups, Choky from ancient Bach, I meant to say...😛 and few more of the great evening we had.

M2-ing the Papa's Koan

so - you already know that ZM is too lay-zee to have own :Pumpkin:

:rofl:

maybe because I don't have time ...... or maybe because is much funnier to have Ikebana style (any new) prototype singing , than having proper boxed and finished gadget

so - every piece of commercially made preamp - I tried lately , to connect to Papa's Koan , is killing da muzak ;

F4 is just too clean .

so - while trying to find where I put some BF862 matched ( which Juma gave me) , and to try last wakoo idea for "will it drive F4 ?" dilemma ....... I gave up of trying active stages which I already have

source is mainly Pioneer PD8500 (xformer I/V then just complementary Jfet buffer ) ;
I used Manu's gift - bloody expensive 4 deck TKD pot , put in small box , as volume control ( no - I don't have PSM LS functional , too :rofl: )

then to F4 , feeding pair of my mighty LC1

fine , but somewhat low in volume , even in my 25 sqm workshop

so - I have these (look down ) ..... and - if concept is good so Papa can sell it to wakkootooblovingjapaneseZMs ......... and if I'm almost Choky from chokes and Iron - it is pretty logical to have nickel toroid repeater coil preamp/gain stage
fed from buffer stage - it's linear from under 20 to over 40k , without any load

so - CD - autoformers - F4 - LC1

no volume control , everything is exactly as needed :rofl:

sound is ....... MAGIC

active stage - as soon I find those BF862 ..... for that idea I need mucho bloody xconductance ......

I hate missing pictures , linked in post ;(

so - here it is - Magic


Don't tell me that was it, Arnie! I mean, you gotta be kidding! That what I had you come up here for? I don't believe it! I mean she, she shows up outta nowhere without a car, without a map. She ain't got nothing but a suitcase filled with men's clothing. How come? How come she act so funny like she was gonna stay here forever? And with no clothes?! No! I don't like it! It don't make no sense at all! No, no, no, no, no! It don't make no sense!


this wakoo place sometimes reminds on Bagdad Cafe

😀
