+1 those transistors might be hard to get, so use bd139/bd140. Alternatively you could use bd327/bd337 for a lower power amp.I've also built one with lme49600 (BUF634 in a different package and marketing ) drivers, which sounds great, but that is expensive silicon.Regards,Jarno.Sent from my Galaxy

THAT corp line drivers? discrete transistor drivers?any thoughts would be greatly appreciated :)-ulfursent from outer space_______________________________________________Synth-diy mailing listSynth-diy at synth-diy.orghttp://synth-diy.org/mailman/listinfo/synth-diySelling or trading?
