opa627 abit ex

currently using

opa 1642 i think been awhile since i rolled my opamps

I've tried the opa627BP on both cMoy v02 standard and rechargeble 9v, using power adapter but no sound at all and chip is put on correctly, don't know why!

By the way, to bad this opa 1642 can't just be put in like other chips, I would have tried it!
