About possible Babelfish J interest
Well , after some time , I'm able and willing again to bring some Babelfish J packages ; Sort of altered schematic , including cascodes (easily avoidable by choice) for input LTP , biased through my green (LED string ) trademark thingie .
Package would be comprised of :
-pcbs (one layer , usual thickness/color/overlay mumbo jumbo)) , 2 pcs,
-2 pairs of matched J271 JFets - in this project perfect
substitute/replacement for Toshiba 2SJ74BL ,
-2 pairs of BC556C bjt LTP cascode critters,
-3+3 more BC critters for various position
-2pcs of MMBF5486 smd JFets , working as CCS for cascode biasing,pre-soldered on pcbs,
-2 pcs of 1uF Philips MKC (polycarbonate, my fave ) , bypass for critical position - cap for Aleph CCS modulation .
so , end of list; few more details :
Output mosfets prescribed - IRFP150 (one effectively as two IRFP240), just one pair , no matching needed .
Soldering of outputs - either through hole or on wire bridges on upper pcb surface .
Due to cascoding , PSU voltage can be freely augmented for several volts. Also possible multiplying of outputs with some necessary ingenuity , but if there is enough noise , I can make daughter boards for paralleling of , say , 3 mosfets , when there is no need for additional ingenuity :rofl:
That would be all , if there is enough interest , I'll proceed in Swap Forum .
Price - not cheap , but also not overly expensive , considering that rest what you need is available even in nearest Tobacco store .
Screenshot of pcb attached .
and , yes , I know that BJ isn't exactly in VFet/SIT/SIC frenzy fashion category :clown:
edit: forgot schm
edit edit : in a meantime , trade thread opened: http://www.diyaudio.com/forums/swap-...ml#post4301409
editeditedit : link to final schematic and parts placement
consider me interested :D
I'm interested ZM
Tell me more. I wasn't in on the beginning of this conversation.
more what ?
I am your eternal follower Papa Koan.
certainly beneficial as chasing your own tail ;)
how about this one ?
trade post here
That is why i am curious .
Why not go for that one and go for the BJ ? because of the outputs ?
matter of choice and 200+$ difference in outputs ?
however , speaking of broad interest/possibility - (B)J2 is still sorta uncovered
that's why that opportunity is one time offer
