I see two 0.1 µF capacitors in the schematic, one screen bypass and one AF grid-bias bypass. Neither one has much voltage on it, and neither value is critical, so if the radio worked before, but doesn't now, there must be something else wrong. You didn't wire the grid-bias bypass to the wrong side of the resistor, by any chance? Or damage one of the screen resistors?
