Quoted from attack7777:Having just done a playfield swap on the upper playfield, yes there is a fuse under there. It's under a bundle of wires along the top of the playfield near the WIN lanes, a little off center. There should be a grey fuse holder screwed into the PF.
It is a 2.5A, 250V Slow-Blow:
