hi
i would like to use my 2sj109 in my diy f4 but i notice it has seven legs as oposed to six when using the normal combination of 108/ 389
what is this extra leg ?
i have not got the output devices yet are there any options here that would drop in and be an improvement on the originals ,toshiba or semisouth perhaps ?
thanks in advance for any help or advice
regards sheafer

thanks zen mod
now i understand ,
so i need the opposite polarity to the or 2sj74
its a shame as i have 8 new 2sj109 bl here doing nothing
i have an aleph 2 clone that is running on high bias 7.2 a and low voltage (25/0/25 sec) for my esl speakers ,perhaps i could convert it to jfet input using the 2sj109
cheers

hi zen mod
i think so ,i should replace the 4x 2sj74 with 2x 2sj109 yes
....
exactly
.....
also does mucho mean remove ?
....
mucho means "plenty"
but - do not look previous schematic where mucho is written
just look at schematic in post #12 where I linked you
and - look at that Algar_emi's pdf - many things will be clearer to you
