I assume the 10 µF cap on the TX audio output is non-polarized. A good choice, which I doubt could be made if you're trying to go 100% SMC. There is a workaround if you're stuck with polarized caps: use 2 in series with the positive sides opposing, & a bleeder resistor to ground in the middle. At any rate, I seem to have the NHRC-micro working again after replacing the bad components. Thanks to all for your suggestions, & if B-D Enterprises ever returns its 1P controller to production, please let us know. Thanks. Bob NO6B
