Threshold T200D?

Is anyone familiar with this amp? Unlike the T200 (I have one of each), the T200D has large VUs on the front. It has balanced and unbalanced inputs. I sent it out to Jon Soderberg for testing/TLC. He went through it no problem, but mentioned that he had not seen one of these either. Inside, the only difference I see is that the T200D has an extra transformer below the main transformer (possibly for the VUs?). Any insight greatly appreciated.
Only difference on the T200 and the T200D is the D which meant Display way back when.

Good listening

Thats a neat piece, we did a very limited number of T200D and 400D amplifiers. Frankly I'm pretty sure we built a good deal more T800D's than all the 200D and 400D's combined.
