Default How safe operating an amp with no fuse?

Let me guess: It sounds much more warm without the fuse. LOL.


No, I wouldn't describe it as that. Without going into minute details,
the overall resolution is much higher.

Question is: Exactly what risks are there in running an integrated amp
or a preamp sans fuse?


You could burn up the power supply, or it could catch on fire. Put the
damn fuse back in.


Could you describe just what condtions would cause the power supply to
burn up or catch on fire (I would not have thought this component to be
flammable!)? As I say, I've been running it a couple of hours so far
and there's been no change. As a matter of fact, a few weeks ago I had
previously removed the heatsink from the output transistors in order to
improve the sound, and there was never any overheating problem.


What you need to do is remove the heat sink again ( that was a good
start). Now pack the heads of matches around the output devices, and
fix a can of lighter fluid close to them. Actually, a couple of
disposable lighters will do as well.

That should achieve the effect you are seeking. Play some music loudly
to complete the picture.
