Hi there,
I'm very new to EasyEDA - but I'm finding it nice and easy and fast to use so far. Thanks for a great bit of software.
I'm also very new to electronics. Anyway, excuses out of the way...
I'm trying to build a preamp module with a bit of gain and isolated outputs so that a single low power source of any quality (phone, tablet, Pi) can drive multiple poweramp modules right up to their 3.6v p-p limit.
So far, I've designed and tested a single channel of the circuit and am happy with the values and the response. So my next step is to generate a PCB.
I'm aiming to do as little "manual work" as possible to step the design from the single channel /tested/ version to a dual channel PCB version to minimise errors. But I've got a little stuck.
Where I have been using the standard TL081 symbol - 4 of them - I'd like to produce a PCB which uses a single TL084. But I'd like to do this without the possibility of errors introduced from manually unwiring the current symbols and wiring in the actual DIP14 package. And from what I've found so far, I can't produce a testable schematic using the DIP14 for the various TL084s I've found under "More Libraries".
So what I was hoping to do now is convince EasyEDA that my 4 separate opamps on my schematic belong to the same DIP (using different pins, of course), and have it automatically produce a PCB based around a single chip.
Is this possible? Or is there a better way I should tackle this problem? - perhaps I need some pointers on how to build a testable circuit based around the TL084?
My tested, single channel schematic is here:

And the full version I've carefully put together from it which is causing me this problem is here:

Many, many thanks in advance for any help offered! :-)
Thanks,
