useful to learn , while using "less good" parts
but , stay aware that they never will do the job as proven ones
also , always take in account Rout and Rload (next stage) , while contemplating about construction and used parts ....... example - Borbely WCF implementation of "same sex" JFet buffer is better than regular "same sex" buffer only in cases when load is heavy , while with more sane (usual) loads , regular one is better measuring and sounding one
again , all parts are good if you use them in clever way .... but there is also fact - when I see 330R as nominal part of Rout , that's simply not in "swiss knife versatility" category, so - "use with care" label is needed

Hi Zenmod!
Because of my Papa is also smarter than their Nelson i could decrease R2 and R4 to 269R and make R6 100 ohms (R out is 1K at original B1 design as you know)
Yes 2sk170bl may be better (i am regretful that i sold hundreds of 2sk170 and no stock left.I have some hundreds of 2sj74 though,i am keeping them ) but difference seems not too much (at least on simulation) and this is mostly 2. harmonic.If there is no difference on blind test i can live with it.
Maybe you can send me some hundred of 2sk170bls( i heard you have ten thousands of them) as free gift
