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 )

The more I look at that layout, the better i like it. Superbly layed out board What is the size of it?

Should be good enough, if it whistles at 300 deg. C

last teasin' .........or not ?

5/5

so proto pcbs are in my dirty hands;
there are few minor mistakes,probably made in conversion from Oly's tango to mnfctrr's protel ; anyway- they're more than good ; nothing what few cuts with knife or dremel can't fix.

I still don't have few elements,and I'm not in so big hurry .....I'll wait few days for some resistors ,just because I hate to solder mess of resistors , if I don't have needed value.....

Nice

saliva 's going..........
