[QUOTE="Mars, post: 98807, member: 817"] Nice explanation Leon! Regarding the resistors in the power supply - each amplification stage has it's own capacitor to reduce hum and to drain away signal coming from other stages - it decouples each stage from the others. The resistor helps to isolate the stage as well as set the correct DC level for the triode to work at. Typically resistors or inductors are used to accomplish isolation. [/QUOTE]
