Hello, i just started to design a new pcb for G9 (1ch layout) . Designing the input's trafo LL1528 layout , looking at lundahl's website at http://www.lundahl.se/pdfs/datash/1528.pdf i saw different trafo connections. At G9 input are conected for + 2,3 and 1,4 for - ( lundahl say 1,4 for + and 2,3 for -

At the out of input's trafo would be 5 for out, 7 to gnd and 6,8 just conected.

Is there a mistake? What happens?

Cheers Fotis
 
Looking the output's trafo LL5402 at http://www.lundahl.se/pdfs/datash/5402.pdf i saw that is 100% OK ( for my litle knowledge). But for my opinion (knowledge) the input trafo looks like wrong connected...

Someone to explain me this tricky connection?


Trying to tell you what i think ( because my English are not so good ) , i give you two pictures.

This is how G9 is conneted on pcb layout http://www.qsl.net/sv3eao/g9.gif

This is how i could connected it if i hasn't the G9 pcb layout. http://www.qsl.net/sv3eao/Image1.gif

Any suggestion about?


Cheers
