Copy-paste ovde, mrzi me da kucam ponovo

Second installment of Plethora of Pinjatas series of amps

Started with this

 

 

[Zen Mod]

which is

 

[Zen Mod]

that gone to T-Bed

 

[Zen Mod]

rails +/-23-ish
Iq 1A7-ish
output DC Offset negligible
LU1014 Uds set to 2V4

BFR (Beauty Factor Resistor) 22R, so OLG max.

thinking to make MC pre of this one

result, Pinpoint Machine - dominant 3rd

set of graphs for 8R Load:

 

 

 

 

 

 

 

 

 

 

 

[Zen Mod]

everything the same;

set of graphs for 4R Load

 

[Zen Mod]

OK, THD levels are ridicolous

But, as intention wasn't dominant 3rd, finally to use BFR position for Sugar Level Tweaking

BFR changed to 270R (OLG goes down, amount of NFB goes down, degree of symmetry between phases (LTP) goes down)

 

[Zen Mod]

so, to repeat:

rails +/-23-ish
Iq 1A7-ish
output DC Offset negligible
LU1014 Uds set to 2V4

BFR (Beauty Factor Resistor) 270R

result - Pinpoint Sugar Machine, dominant 2nd, THD Levels still ridiculously low

set of graphs for 8R Load:

 

[Zen Mod]

everything the same;

set of graphs for 4R Load

Kad ce ovo cudo kod Wolija na saslusanje? 

Mislim, sad, kad zamislim sve ove ampove, vec ima izbora, da ne zna covek koje da izabere... Ne znam zasto, ali setih se ovoga:

pre 17 časa, Zen Mod reče

BFR (Beauty Factor Resistor) 270R

result - Pinpoint Sugar Machine, dominant 2nd, THD Levels still ridiculously low

So, soundwise: SET with cojones. 

[Zen Mod]

Aren't they all?

Yup...ali koji SET?
Direktno grijane triode za jaudiofilčine s pedigreom ili one druge, za nas slabije jaudiofile?
