anyone know what size fuses these are?

[Gtr_tech]

5x20mm metrics?

[Jazz P Bass]

Agreed.
They appear to be "ceramic" fuses, 5 x 20mm (width & length), hense the cloudy look.
Ceramic fuses help to contain any "flash" when they are overstressed.
FYI: The fuses are labeled :
-F2A: this a "fast acting" 2 amp fuse.
-T1A: this is a "slow blow" (ie: time delay) 1 amp fuse.
Please note that the fuses have a "voltage rating" of 250 volts.
As this is what is installed from the factory, I would recommend that this rating is observed, when purchasing replacement fuses.

thanks guys!

looks like a t1ah for some reason is that a 1 amp timed or a 10?

[Jazz P Bass]

The photo is hard to read.
If that is indeed what is marked, then , yes, it is a 1 amp slow blow fuse.

thanks dude!

Bt the way, if any fuses are blown, you can expect (in all probability) to find one or more bad power tubes
