[sdiy] Output impedance check...

[Justin Owen]

Was hoping someone could take a quick look at this to double check my assumptions?

Standard op-amp buffer as output. Input is from 'in-circuit', output is to the outside world - yes, where dragons be.

Is the impedance of the jack output still 1K even though there is an LED driver also hanging off the same op-amp output?

Any real reason why not to do this under 'normal' use?

Thanks!
