yea I should have those at the house or definitely something that will work there. Those are filter caps in the dc power supply section meant to filter the AC ripple out of that diode bridge next to them. Typically if the top of the caps is bulging it means they've been hit with a higher voltage than they are rated for. I would not be so concerned about a slight bulge as I would be a shorted cap or leaky (electrically) that would eff that up. Easy nuff to test them anyways.
Years ago we used to initiate the new guy by plugging a few of them into his bench ac strip so when he turned his bench on it went KABLOOIE
They don't like AC
