Pumpkin Preamp - Perfect for F4
Default Pumpkin Preamp - Perfect for F4

there it is
schm and render of pcb enclosed

now I'm waiting for pcb protos and heatsinks ,just to tweak some values - this time I'm lazy (or spoiled?) to make Ikebana prototype

I don't like to use nag nag protoboards where I can't see connection, contrary to Oly......pcb wizz with 100 yrs of needlepoint experience

this preamp is in fact Steen's wish, sorta half UGS bla bla
seems that this days I can't make anything what Papa already didn't

why that reminds me on old story about pigs and pearls


there is proverb in my native........"there is no bad swill for good pig"

lookie
lookie

double sided pcb , in fact just several traces on upper plane


this preamp is intended (Steen again) even for F4 driving, with little more juice even headphones ; I'll certainly try it on my spks (sorta biggg headphones with 16 ohm impedance )
