Have few boards with that type of pattern left from cmoy : http://www.mindresearch.com.hk/img/big/29110.jpg . Anybody has layout for Linkwitz or Pint or both? If they are on one board together its OK too. And maybe there is opamps for PINT that fit in protoboard holes? (making life easy

)
thanx.

the opamps used in the PInt are SOIC package. Thee are no a direct it to the protoboard holes but it can be done. Search for member sijosae and his headphone builds(they're in a different forum) He uses SMD components in protoboards.

But the pint uses lots of SMD and it would be extremely dificult if not impossible to build one in a protoboard.

I have built one with big size components like Cmoy has. Soldered opamps on 8 pin opamp socket with help of wires cut from resistors but Its not right way. Problem is that my input ground is too long because of polypropylen caps on +12V and -12V amp power are too big

. Guess what happened? Ground is hot. Maybe opamp is broken because I firstly soldered IG and OG to one

I would expect it to be extremely difficult to build a PINT (with the AD8397, at least) on protoboard because it involves high speed op-amps. For stability at these speeds, board design becomes extremely important, and you can't really do much on protoboard about that.
