Oh, and something else:
On Atrend ATC-6631 cards (with YMF71x) there are two 220 ohm resistors labeled CB12 and CB13. Now why these are labeled CB (Bypass Capacitor), or why there has to be be a cap or resistor here in the first place is beyond me, but when combined with the output impedance of the XR385 (about 1K), these will attenuate the signal by about 15dB. It's probably a good idea to remove them, especially when using the output mod I described in my last post.

edit: Labway cards actually have capacitors here.
