  2. Thanks for keeping up this amazing site!
    Just built this, not managing to get audio through... any success with this? been trying to troubleshoot it but a bit beyond my knowledge, so wanted to make sure the layout is correct. thanks!

  3. Building this up now & I think the layout may be missing a connection between 9V (thru D1 + 47R resistor) and Vcc rail. Adding a jumper wire from 15V to 15W fits with no other changes.
