Was playing 1977 big deal. Quit working while playing. The 15 amp fuse blew on 24 volt line. Put another fuse in and now it blows immediately when I turn machine on. Any ideas. Thx

"If a coil is locked on, this fuse will often blow. Or on games with AC to DC power conversion for the pop bumpers, the bridge rectifier has shorted."

My 1974 Strato-Flite has factory DC-converted pop bumpers so I would assume your does too. Possibly a bad rectifier of some sort?

Is it a slow-blow fuse?

Check for burnt coils or a shorted bridge rectifier.
