#2 is NOT an Allen key screwdriver. It is a spline driver. Many
many spline setscrews have been mangled by sticking allen keys in
them...

Extension cables allowing you to operate modules out of the
deck and give you access to their bellies are very worthwhile.
The IF module cabling as is can be twisted enough to give you access
to the bottom, and there would be little call to get extension cables
for the power supply, but I've found RF deck and AF deck extenders
very useful. Without these, tube socket test adapters to allow you to
probe around the tube pins are very handy.

The most useful tool of all: a second working 390A with modules
for swapping out and making measurements on!
