Derick,The 5V4G is an indirect heated-cathode rectifier and the 5U4G is a directly heated cathode tube. Maybe the "flash" you see with the 5V4G is the heater element warming up.
When you said that you replaced the Philips 6X4 with a Mullard, you mean a Mullard 6X4/EZ 90? The 6X4 type is indirectly heated. So. once again, you may be seeing the heater filament light up, initially on fire-up.
Just another WAG in the desert...
