Building my first tube amplifier, on a tight budget.

The power supply section was built around a salvaged Philips radio power. transformer, as mentioned earlier. As my transformer had different secondary windings than the one recommended by the AX84 project, I had to make some changes to the circuit. I worked out the new value for the main voltage dropping resistor using a combination of IRL experimentation and Duncan's Amps' PSU designer.
