CSXCCSwhatever BOSOZ by Igor

Zen Mod · 2nd September 2007, 08:17 PM

project started several yrs ago,when Igor was green , by purchasing all pcbs from KK , along with wrong schmtc ....

no need to say- mucho xpensive parts , time and passion were on line , but without much results - poor bstrd can't sing with wrong resistor values....

in a meantime , we (Igor and humble me) started our not just audio friendship and I decided to help him to make thing work ;

with help of resident boyz'n'grlz from CSXCCSwhatever BOSOZ preamp thread (Metalman and others) I was pointed on useful and working schmtc ,so - after much

(primary related to my now already known attitude to these blue fashion tv pcbs) I made necessary fixin' and tweaks , so Igor is now already several months happy owner of cascoded x-ed CCS loaded BOSOZ ;

Comodore plastic case is for two lill' donuts,along with RFI mains filter ;

nice lookin' case is Igor's handwork ,also as 95% of wiring, soldering etc .

this time I was (just as usual ) smart "back" (I know that if I wrote *** it will be showed as ***

)

anyway - 4 pics of previous lost case in nice case ;

when I persue Igor to place PassDiy sticker on top of it ,I'll post that too

mebbe I'll persue him to participate something here,instead of just lurking ....

hehe

Igor told me that he will not make

;
he'll wait for my toob X preamp

toobz are better anyway than these 3-legged fuses ;

they usually have more legs,so it's logical they are better sounding .
