Before you ever touched that can, were the metal can tabs connected directly to the metal chassis or were they connected to a brown insulator that was it's self riveted to the chassis?

Some cans (especially B+ doubler lytics, and cans in sets with a B- rail) are designed so that their negative terminal/can is not wired to the chassis (floating can), but some other supply terminal/rail at a voltage different than the chassis.

If you connect the a can that was meant to float at a different voltage than chassis potential to the chassis it will royally mess up power supply operation, and disturb many other circuits.
