When it's "done" I will sticky it..

CAUTION - TUBE AMPS CAN USE 500+ VOLTS DC POWER WHICH CAN KILL YOU. BE CAREFUL, ASK QUESTIONS FIRST.
OK guys, here's another capacitor question.
In earlier posts we learned that coupling caps block DC voltage and allow AC voltage to pass from the preamp tube anode (plate) to the power tube control grid.
So, if capacitors block DC voltage, how can they be used as DC power supply filter caps that smooth out pulsing DC power? I do know power filter caps are usually polar electrolytics and coupling caps are usually non-polar film or paper-in-oil caps. Does part of the answer lie in this difference?
GordonW and Kegger,
I am assuming thermistors are not directional (e.g., can be installed either way)......correct?
Thanks,
Scott
This is a picture of an axial lead polar electrolytic capacitor. The positive end is marked with a "+". Pay close attention the polarity when replacing polar caps. Installing them backwards many times will explode them once power is applied.
This is also a holding spot for expansion of this thread as needed.
