Ok, Ive got the schematic from Pinballfixers site - thanks mate!!
I dont have the manual so its a bit hard for me to follow whats going on here,
Let me get this straight - F1 keeps blowing, this is a 5A Slo Blo.
transistor that keeps blowing is Q1, this happens at power up, but you can hear a hum?
Now with your DMM set it to 200ohm setting ( this will probably be the least resistance value on it), check diode D21 on the PPB. It should read low resistance one way, switch the test leads over and you should get infinite ( will go off the scale) reading the other. if you get low both ways, this diode is short.
The feed in to Q1 is connector J8 pin 11, - out is J8 pin 12. make sure there is not a short across these. Also R19, put meter to a higher reading and you should get 220 Ohm ( or VERY close).
measuring resistors in circuit can be decieving though and sometimes you have to lift one leg.
Make sure TIP36C is in the right way round.
If you do all this and this checks out, then the circuit for this transistor is fine and we need to look elsewhere, but lets eradicate this first
