WYSA or Wierd Yard Sale Amplifier

A friend picked these up for me at a yard sale. This is a weird 6L6 Push Pull amplifier with two chassis. Interesting use of variacs and construction advanced DIY. If you have seen something like this let me know what you think.

Here is the power supply chassis.

Here is the Push Pull 6L6 section with four 12ax7a and two 66c7 tubes. The output transformers are from olsen electrconics and are fairly small T-355.
