  8. audioguru attached a file to the thread Going to build this from the learning page.

    You can use this circuit with modern hifi opamps. The OPA134 single, OPA2134 dual and OPA4134 quad hifi opamps are good and do not cost...

  9. kubeek rated Nigel Goodwin's post Agree in the thread Going to build this from the learning page.

    They are SERIOUSLY needed on a mixer, and even on a decent HiFi they make good sense - but on a mixer they are absolutely essential - a...

  14. MikeMl replied to the thread MOSFET circuit question.

    I put the R2/R3 voltage divider there to control the peak gate voltage on the PFET. If running on 12Vdc, without R3, the peak Vgs would...

  15. AnalogKid replied to the thread MOSFET circuit question.

    Because Mike added it. I think it can be eliminated. Because I focused on a semi-isolated TTL output. Your suggestions is better....
