All the fuses are correct . In this case the .20c transistor is protecting the $1:50 fuse?? It is the fuses fuse? I have checked and checked for shorts , thus far no good. As it happens after about 1 hour of play time it blows. I'm thinking short or maybe heat related.Not real happy about continually changing transistors as the board is under heat stress.I am concerned about tracks lifting. One of the switches is the play field tilt..I would not be fussed if it was redundant. Can I take this out of the circuit without stuffing thing up? Also thinking about temporally fitting a socket so I can change the transistor easily.
