If you want to build a ship, don't drum up people to collect wood and don't assign
them tasks and work, but rather teach them to long for the endless immensity of the sea.

And the interesting part will be to build the DC power supply for the many voltages
(-270V, -130V, -60V, +140V, +270V) and the heater supply.
A good source for
information on how to do that would be an older edition of the ARRL Amateur Radio
Handbook. Those can be found, from used book dealers. I have a 1954 edition that would do
well, though one from the 1960s is likely also good (perhaps better since the earlier ones
would have vacuum rectifiers, which in a newly built supplly isn't optimal).
