Amplifone Deflection PCB - Spot Killer "ON"
Hi;
I rebuilt an Amplifone deflection PCB as I always do but this one did not come through like the others.
I have it in my Star Wars that I am building and I get deflection chatter but the spot killer is on as well.
I tested and got voltage on the X and Y outputs - just to make sure I swapped it with a known good working deflection PCB and the game has a nice display. I put this one back in and "spot killer on".
I tested the transistors again just to make sure and they all seem to be OK.
I don't understand why I would have deflection chatter and still have the spot killer on.
Is there something with this situation that rings a bell to someone?
Any hints would be greatly appreciated.
Thanks
Jeff
