FWIW all those voltages look normal. The plate v's on the output tubes being 2V different suggest one tube's drawing a good deal more current than the other. You could do a bias current test the approved MEF way - measure resistance of each OT primary winding, then measure voltages across those windings, current = v/r.
Have a dental mirror? Scan the back of the main PC board, especially where the leads to the output tubes are. Make sure you don't see any signs of fire, arcing, like that. What's left? Speaker - unlikely but possible. Fender to their credit puts a rather heavy duty speaker in these. Drive a known working speaker from the amp & you'll know fast. Output transformer? Personally I haven't had one go bad, but others have. Lucky Fender has QC connectors on OT leads so you can disconnect the one in the amp & hook another known working OT with clip leads.
