PC power supply fuse - T6.3h 250v engraved on end

Load fuses are rated. The ratings will be marked at the PCB, very near to the fuse holder. Do not use a fuse, which have more ampere ratting than specified. It will make things worse. If fuse burns out, as soon as the set is switched ON, be sure that there must be some shorted component/s at the power supply regulator section circuit. Check and rectify the fault first, before inserting an other fuse of same rating.

TRY MAPLINS OR A ELECTRICAL STORE OR EVEN A DISCO SHOP WILL STORE THESE FUSES.
TAKE THE OLD ONE WITH YOU AS THEY WILL NEED TO KNOW IF IT IS FAST BLOW CAP ON EACH END WITH A SINGLE WIRE INSIDE OR NOT (IS THERE A SPRING AT ONE END INSIDE THE GLASS TUBE THIS IS CALLED A SLOW BLOW FUSE).OR IS IT IN A CERAMIC WITH A METAL CAP ON EACH END.
HOPE THIS HELPS

thats a 10 amp fast blow fuses rated for 250v

You can get them at any Radio SHack Store


Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

There usually no fuses on a M30 dosatron unless it's the "L" shaped supplemental supply board which has a small 250V, 6 3/4 A fuse (half the size of a normal glass tube fuse). Most boards use a similar size but rated at 4 amps for the PC board power protection. The only other fuses (older models) have big 10 amp jobs for the main power to the heater elements. But this has been replace with safety relay and or high thermal limit breakers. you should be able to find both at a hardware store. The smaller fuses at Radio shack or electronic store.

It is a Fast Fuse Glass type 5 x 20mm, 2A, 250v. Magellan 4250 can only take 1A of current at 5Volts Radio Shack

The microwave oven use a slow-blow fuse. If you look on the around the end of the fuse, you will be able to tell what size it is. Example (250v 3Amp) Your fuse may be found at Hardware stores in the electrical isle or a Radio Shack. If you found my suggestions to be helpful, please rate my solution. Thanks D. Lange

Take the subb to radio shack, somthings short circuiting it out and its blowing the fuse for preventing interal problems,

These fuses are most likely 3 Amp fuses. Please note that if the replacements blow as well, that there is a problem within the amp section that will require repair.

It is written on the sub. You can also take it out or look at the spare which is taped to the power cord wall plug. I believe it's T1A 250V fuse

the fuse will always blow if there is a shorted component. the horizontal output transistor may be the most likely culprit, if you are not a technician, have it service by a qualified one.
