Is it safe to run two sets of speakers on a Fisher 400 using a Passive Switch Box (with protection) like the one in the picture? One set of speakers would be vintage Grundig's (see photo) from the 1960's that I believe are 6 ohms. The second set of speakers would be a passive Pioneer S-W33 Subwoofer (see photo) that is 8 ohms with duel speaker inputs. If it is safe, do I run the Fisher 400 in 8 ohm or 4 ohm mode? Thanks, Mike
Without modifying the unit, is there a safe method to use a Fisher 400 just as a preamp without damaging the output transformer? I see it has a Speaker on/off switch. Does turning it to the "Speakers Off' off mode solve this issue? Please no guesses, only reply if you're 100% certain. Hope I don't sound rude, just cannot risk damaging the unit.
