Dcdong rec tube6/19/2023 ![]() It might be less than 1% but I still want to know and am interested. So there is reason to believe pulling these two tubes and unloading a good bit of power might make more of a difference in this scenario. ![]() ![]() It has two 5U4 at 3.0A each which total more than 3 times the current draw of the 5AR4. Now lets look at a Dual Rectifier amplifier. It is a 5VAC circuit made for a single 5AR4 which is 1.9A draw. The 6.3VAC filament had a 1/3% to 1/2% bump in voltage when pulling the rectifier tube. It is a bit different in function and design from the Dual Rectifier but proves the point. If one of those circuits is unloaded the power can be diffused to the remaining loaded circuits, not 100% but some of it. The transformer is designed to transform from the primary a specified amount of power to each secondary circuit with tolerances. No it is not because they are supposed to develop power. So by your description there should be no voltage/current /power to the secondaries. The secondaries are also isolated from the primaries. Yes the secondaries are isolated from other windings. You converse as if your word is absolute but it is not. Like pointed out in another thread it seems you always know everything yet you do not.
