converting a Peaberry from 60/40/30/30 to 30/20/17/15

Postby tannebri » Mon Apr 27, 2015 5:45 pm

I wish to convert my Peaberry V2 from 60/40/30/20 model to 30/20/17/15. From the schematic and coil winding sheet I see I need to re wind T3 and L9. But also need to change C42 C44 C46 and R47. What size are the SMD components 0805 or 1612 and what spec are the capacitors.

Regards Brian

Hi,

The SMDs are 1206. But I am curious. The kits ship with all the components necessary to build any version. You should have everything you need (except perhaps a bit more wire to rewind the transformers and chokes).

It was purchased a ready built. So I do not have the other bits many thanks are the capacitors anything special material?

Ah, OK I see.

I really don't know. When I needed addition components I simply picked the best ones I could find on Digikey.com.

David, would need to chime in on what the exact specifications are for the resistors and caps.
