Hey digi!
nice to see you still helping out other DIY'ers.

Few Q's for ya.

What improvments are seen with this new PCB over the first ones you did?

sorry to say from a new job and lack of time i havent been able to build my BPA-200 with your boards i bought from you.

As well guys Digi01 is a great person to buy from, have no regrets when you do. Im in Texas and it took roughly 2wks to get from him to me.

Hello Evilsizer,
Thank you for your nice words.

The new version is a compact device.the feedback and the others resistors are all 0805 smt packaged,it will get extremely signal route.the bigger parts C1,C2,LM3886 and coupling cap will perfect fit its station.more gnd connection trunks.

kind rgds,
Zang
