That issue will happen either from the 2A3 insertion as I mentioned, or from backwards 100uF/450V caps, which act like a short when installed backwards and destroy the 130 ohm resistors.
If you use 1/2W resistors, they will probably last a few days/maybe a week. A 1W resistor around a year or two maybe, and a 2W resistor indefinitely (other than failure from fault conditions of course).
