The 400 has 6 6550 power tubes, similar to an Ampeg SVT.

The 400+ has 12 6L6 power tubes. Can't think of any heads set up like this, off the top of my head.

Also, one smaller difference is that 400 has a 6-band Graphic EQ, whereas the 400+ has a 7-band Graphic EQ

Edit: Turns out some of the early 400+ units had the 6-band GEQ, but most have the 7-band.
