Can I read 6DN7 Tube Amplifier Circuit Design on EtoBox?

6DN7 Tube Amplifier Circuit Design by Juan Sánchez Moreno is a document available to read on EtoBox.

What is 6DN7 Tube Amplifier Circuit Design about?

The document shows a circuit diagram for a tube amplifier with three variations on the filament power supply. The first uses a 6.3VAC transformer to power the filaments. The second adds 100 ohm resistors in series with each filament leg. The third uses a voltage divider with a 68k resistor and 0.1uF capacitor to elevate the filament ground potential.
