I would think the fuses for F1 and F2 were placed in the wrong order. If they were swapped with each other they would have the correct values for 120V operation.scottm_dj wrote: ...
US fuse F1 should be 1/2amp...and is is 1/4. UK spec as I suspected
US fuse F2 should be 1/4 amp...and is is....very interestingly T500 so 500ma which is 1/2 amp. Uk spec is 1/8 amp. This could be an issue.
Fuses don't work quite like that. If for the moment we assume that there is no fault with the equipment, if you put in a fuse with a higher current rating than specified, the equipment will work quite happily. The circuits only draw as much current as they need and it will be less than the fuse rating. So in a properly working device the fuse does not limit anything. The only issue in that case is if a fault occurs and the fuse has too high a rating, then your equipment is not appropriately protected and may draw too much current and cause further damage.scottm_dj wrote:None of the fuses appears blown but i bet F2 is the tube fuse and didnt have a low enough value in it. What do you all think?
Now for the other case where you have a properly working device and you install a fuse that has too low a current rating, then the device may draw more current than the fuse can handle and the fuse will blow/break.
So after all that, it is more likely that the F1 fuse that is only rated at 1/4 has blown. As it is protecting a circuit that may draw up to 1/2 an amp.
If none of the fuses has blown, then it may be that you have a more serious issue.
I think you need to properly check the fuses to determine if they are blown or not. A visual check might not be sufficient. If you have a multimeter you could remove the fuses and do a continuity check on them. Or just replace F1 and F2 with new fuses of the correct value.
If they are not blown, and replacing the centre channel tube does not help, then you may need to get the MET1 checked by a technician.
My money is on the F1 fuse being blown.
