Having a devil of a time finding one. Anybody know where I could get
it? Looks like it was the glass type. Don't have the original.

Fuses come in only a few (3-4 at most) physical sizes.
Should be pretty easy to measure the fuse holder and
figure which type it matches.

Richard,

Thank you, but it is more the amp/volts and size together I can't
locate...

Jim,

The fuse is likely to be either the standard European size (5x20mm) or
US size (0.25x1.25 inches) The 7A 125V fuse can be substituted with a
7A 250V fuse, as the voltage is a maximum working voltage, not the
voltage it must work at. The hardest part is to determine if you need a
fast ("F" type in European or 3AG in US) blow fuse or a delay type ("T"
in European or slo-blo in US) fuse. a 6 or 6.3A fuse would be safe to
use but might blow at high volumes, especially if you have 4 ohm speakers.

Often there is no marking on the board telling you what you need. It
is safer to go with the fast blow type if you are not sure, but the fuse
might fail for no reason if it was supposed to be a delay type. It is
most likely to fail during a turn on surge.

If your local Radio Shack or TV repair shop can't provide you with a
fuse, you can go to www.digikey.com or www.mcmelectronics.com. I prefer
to stay with established brands of fuse like Littlefuse, BUSS, or Wickmann.

If you want to be absolutely certain, you could always order one from
Yamaha, though probably at a high $ cost.

If it is not marked on the equipment somewhere (which
is very rare, in my experience), then you will need to
get the user or even service documentation to discover
the fuse rating. The voltage rating is determined by the
physical size of the fuse and likely is not of real concern.
It is the current (amps) rating that is critical here.

Have you diagnosed and repaired whatever made the
fuse blow in the first place? Else you'd better buy a
couple of boxes of fuses! :-)

Higher voltage, within reason, is just fine. I'll bet 250V fuses are
abundant.

Use a higher amperage if you have to. 8 amps is probably indistinguishable
from 7, since fuses are rather imprecise things. Use 10 if neither 7 nor 8
is available.

Bad idea. Stick with the original, or as close to it as possible.

Actually, here is what it says just next to the fuse holder:

F101 7 amp 125v
LL7451-7
gcmk-81x

So what exactly is the question? You have the current rating
and you can measure the fuseholder. What other info do you
need?

I'm guessing all the available fuses were rated 250V, which, as it turns
out, is not a problem at all.

Where to buy it...

You can use a 7 Amp / 250 Volt fuse in your amp.

7Amp fuses are not commonly stocked and many times it is the aumotive
type (32 Volts) that is stocked.

Using a higher voltage fuse than specified may increase the cost
(slightly), but has no safety implications. Using a lower voltage fuse
risks that the fuse will not completely interrupt the current when it
blows.

Radio Shack? I personally don't like the store much, but if you need
something very simple, like a fuse, they'll likely have it.

Thank you all. I found them at my local hardware store (this guy seems
to have everything). Bad news is looks like the amp has a blown
channel which is beyond my expertise. Guess I'll toss it.

Sell it as-is ebay.
