Synergistic Research Orange Fuses

BTW, while I've never owned any of the stereo tube tuners made by the original H. H. Scott company, such as your 350A, I've owned three of the mono tuners of that era (310C, 310D, 311D) which provided a "multiplex output" jack, and so could be used as stereo tuners in combination with a Scott LM35 or 335 multiplex adapter, or a Fisher MPX-100 multiplex adapter (all of which I also owned). And I believe that from an electrical standpoint the 350A was essentially a combination of the 335 and one of the mono tuners.

This was mainly during the 1990s, and I recall all of those models as producing really nice sound, especially the 310D + external multiplex adapter. Although as might be expected their weak signal reception capabilities were not of the same calibre as those of the far more expensive Marantz 10B (stereo) or REL Precedent (mono with multiplex out jack).

Al, do you think it might be wise to remove the fuse in my Scott tuner?

If you mean "remove the fuse" in the sense of simply taking it out in order to put in a different one having similar ratings I don’t see any risk. Assuming, that is, that the ratings of the replacement are accurate.

But if you mean replacing the fuse with a wire or some equivalent bypass, I would say absolutely not!

The protective functions provided by a fuse would seem to be all the more important in the case of a nearly 60 year old component than in the case of one that is currently produced. Also, since a wire bypass of reasonable gauge will have lower resistance and hence lower voltage drop than any fuse (albeit the difference is likely to be small), per my previous comment the result may very well be sonics that are worse rather than better, in the case of a component from that era that is being operated at contemporary line voltages.

Keep in mind that when the Scott 350A was designed, ca. 1961, AC line voltages were typically several volts lower than they usually are these days.  So to whatever extent sonic differences between fuses may result from differences in resistance and hence voltage drop, lower fuse resistance may result in worse sound from that component, not better sound.

Just a thought.  Regards,
