Thank you!!!That's crazy that they have all those fuses inside. Fuses should be user accessible but thats just my opinion.
Old Marshalls had an AC fuse (aka Mains) and a DC fuse (aka HT which means High Tension). Old Fenders only had the mains fuse. Yep. ONE fuse. That seems like a lot of unnecessary fuses in that pic.
If it specifies a fuse type then use that. If it does not say Slo Blo then you shouldn't need it.
