But, I can twiddle knobs purdy good. Of course, that was way back in the day, long before the rheumatism set in. CBD helps with that, too.
    Lasermaster1977 is graciously being very helpful for achieving my goals.
    Nevertheless, I have no doubt that RTFMin' the pdf's will help in that respect.

    @TheHermit: This or a variation of this circuit may help you to convert audio signals to ILDA standards. I just posted it today in another thread on PLF as well. (Question about X and Y differential ILDA signals) If the DC offset 10K input and the 50K variable resistor are eliminated entirely then the circuit becomes a single-ended (unbalanced) inverting amp with a gain of 2 (change the gain via Rf to suit your needs), the output which becomes the input to the final ILDA differential (balanced) outputs for X & Y. Shown here are X and Y channel circuitry.
