Hi Randy:

The power transformers are pretty easy to acquire. Just look for one that
is the approximate size. Often you will find nice substitutes in old tube
test equipment that no one wants. I just took apart an old HP square wave
generator and it yielded a perfect replacement for a rig. It would have
worked nicely in the AT-1, also.

Meters are critical for the right look. You can make new scales using a
number of free software programs.

Nice rig. Beware, though, the power output is only about 8 watts, so do not
expect 35 watts input and 25 watts output.
