Welcome to the Phorum MoraleBuddy. Don't trash the W-4AM. not as popular as the others, especially the W5M but a W-4AM just sold on ePay for $179, and it is missing the tubes and power transformer!

Correct tubes for this are 5V4 Rect, (5U4 will work for test purposes, but the 5V4 with its heater style cathode is better and safer), 2X 5881 (6L6GC) for the output and 2 6SN7s as voltage amp, phase invertor (cathodyne) and drivers.

Change the power supply filters before attempting to power this up and have a load on it. The WA-P2 Preamp gets its power from the W-4AM or any of the other Williamson Amps in the Heathkit Line.
