Hi All,
Can anyone who has built a G7 mic help me? Jakob?
I'm looking at Jakob's schematic on his website and it shows two 2u2 capacitors, however in the PCB layout I can't find one of the 2u2 caps! (The one that's shown in the schematic going to ground.)
Also in the schematic I see a 100uf/35v electrolytic in parallel with a 1u/63v non polarized cap but....the PCB layout seems to show only a 220uf/25v cap here.
Thanks in advance,
Freddy
 
Hi Freddy,

On the parts overlay of the mic board itself there's a 2.2uf and a 1uf/160V cap. I think the 1uf is what's the other 2.2 on the schematic. IIRC the other 1uf/63V cap, the 100uf cap, and the trimpot were optional, weren't they?

Good luck
 
And if you buy good quality audio grade caps for the 220uF/35V then you won't need the 1uF poly in parallel.
