I want to replace the 2 big blue caps on my Tron transformer assembly. I'm guessing these arent the same as the infamous Atari big blue caps, and all the manual says is 60Hz. Can anyone point me in the right direction?
 
I have a Tron with a amplified ear bleeding hum. Swapped my pcb,audio amp, harness and pcb with know working parts and still no cure. Would replacing these caps be a good next step?

Why do you think they need to be replaced? I never heard of anybody replacing them.
 
I'll give this a go then. Forgot to add I also have a black line scrolling which I assume is a hum bar.
You might double-check all of your fuses before you order. I know in other Midways (Ms Pac) a hum bar and buzz can be caused by losing one of the power fuses, causing the voltage to float. Check the fuses with a meter and check the connection between the fuse and the holder. If that doesn't work, caps would be a good next step.
 
The MCR adapters (like Arcade Shop sells) do not bypass all the caps. The smaller 3-pin connector is already unregulated DC voltage from a couple diodes and one of the caps.

Yes, those caps can cause a hum bar (so can a lot of other stuff). There's also a third cap in that assembly. An old oil cap....I had it cause a hum bar once.
