In a tube Guitar amplifier the 5U4 rectifier tube warms up fast before the 6L6 's draw plate current this lets the DC plate supply voltage go higher than the filter cap's voltage .A bleeder resistor will work but will waste a lot of power. I could put a time/contact in the center tap of the high voltage winding. My friend said to put a Thermistor in series with the 5U4 Rectifier filament. This will slow down the warm up of the rectifier and let the 6L6's warm up first. The question is, will this be bad for the 5U4 rectifier tube ?
