Evening All ,
Blows F3 about 3 seconds after power up . Spot killer comes
on before F3 blows . It appears that both the diodes(?)on the rectifer
board are blown . I have switched several game boards and a/r boards
with the same results .Would like to replace with switcher but how do
do make the 6.3 and 10.6 voltages out of 5 and 12 volts?
I have several other power bricks that use a single bridge
rectifer instead of the board mounted diodes . can this be done in
place of the rectifer board ?
The other power bricks also seemed to be keyed in
different locations - pin 8 , pin 11 , so just swapping bricks is out
of the question as asteroids isnt keyed and the voltage pin-outs seem
to be different.
Any and all help or direction would be greatly appreciated
.. thanks in advance for your time . mike
