Nope.  I've been to the site twice, but did not transfer the photo I
took to PhotoCD.  (Perhaps this year I'll buy a digital camera....)

Looking at the glossy for a Harris DX-50:

Power Consumption:	59 kW or less (typical) at 50 kW, 0% modulation,
			88 kW or less (typical) at 50 kW, 100% tone modulation

Power Factor:		0.98 typical

The PA runs on 480-V three-phase power; control electronics run on
240-V single-phase.

> kW-D/5 kW-N) and by $0.15/kWH. 

According to Mass. Electric's tariffs, a 90-kW constant load receiving
standard service would pay about $45,000.  A time-dependent
(peak/off-peak) rate would probably cost less, and interruptible
service would cost even less than that.
