Mark Levinson 533H Amp fuse information


Have a ML 533H amp. It's about 4 years old. The fuse ( I assume its the fuse) in the right channel blew about a month ago after a power surge from my utility. Yep had amp plugged into Tripp Lite surge suppressor; Surge suppressor was toast after the event. Used center and left channels for stereo playback until I had the time to investigate/replace fuse.

Yesterday tried to play some tunes and nothing from the amp. Power LED was on.  Preamp was working fine.

Question: I would like to order replacement fuses for the 533H before I take the cover off. Anybody know the fuse info: brand type, amperage, etc.  Would prefer to replace factory fuses with the same model. Not really interested in "audiophile" fuse replacements.

What's the difficulty in replacing the fuses? I do have electronics experience.

Define surge.

No surge protector device (SPD) will protect from a power company’s over voltage event. SPD’s are designed to protect from a voltage transient that lasts only a few milliseconds. A good SPD will respond in one nano second or less to a voltage transient.

As a rule a fuse will not blow open from a voltage transient or from an overvoltage event. What blows the fuse is the damage to the circuitry that may have been caused from the voltage transient or overvoltage event.
