The B50 expects to see an 8 ohm speaker load and the M760 expects to see
100mw at 600 ohms on the 'music' input. Any 'sparkies' with an opinion on
how to match up these devices?


If the B50 provided an unbalanced output (one side of the speaker is
returned to ground, just hook them up. It will work fine.

If the B50 puts out a balanced output (speaker floats, not connected to
ground), go by your neighborhood Radio Shack ("You have questions, we
have blank stares") and get a 273-1380 audio output transformer. Hook
the 8 ohm side to the B50 and one-half the 1K ohm side to the M760.
