Can anyone identify this...

The title of the Youtube clip below says it's a modified dynaco ST-70 and PAS 3. The ST-70 is easy enough to identify, and it looks as though his PAS 3 is under his ST-70 on the shelf below. But I can't make out what is next to his ST-70, is that a heavily modified PAS 3? I haven't seen it before, but I'm interested to know.
