so its still blowing F6 with all the other fuses removed??
If its measuring 5 ohms DC on the primary (same as your Meteor transformer) then the primary winding is most likely ok.
Sounds to me there could be shorted turns in one of the secondary windings, though i could be wrong... but if the F6 primary fuse is still blowing with no secondary fuses in, that does rule out any of the bridges or diodes.
You could probably try a slightly larger fuse, say 4 amp or maybe a 5amp fast blow should be safe enough. If the bigger fuse still blows with no secondary fuses in then transformer is very likely stuffed.
