Home Depot called... They want their extension cord inventory back.BTW, if anyone wants to see the most gloriously dangerous use of one of these systems, here are some photos circa 2005 that I will provide without context. Let your imagination run wild.
@FMEng Was the Bogen an MX60 with two 8027A's for its output stage and 3 GZ34 / 5AR4's for its rectifiers, 2 for its output stage and 1 for the remainder of the amp?I bet that Electro Controls, six channel "portable" dimmer weighs in at 100 lbs. Those autoformers were solid copper and iron.
At the age of 13, I started out by running a Davis dimmer and slider patch, very similar to the one pictured above. That, and the Bogen 4 channel PA system next to it, were the bugs that bit. Obviously, the disease is permanent.
It was solid state, a CT-60 "Acousta Master," with a four band equalizer and compressor. It was fairly new when I got my hands on it in the 1970s. That thing was used at least 20 years with not so much as a scratchy pot. One weird thing I remember about it was that the mic inputs were XLR male. I guess the idea was that mic cables would all be female to female, so that you'd never have the wrong end.
The older Bogens, made in Paramus New Jersey were FAR better / durable than the later models assembled in Mexico with inferior components.It was solid state, a CT-60 "Acousta Master," with a four band equalizer and compressor.

The lowers bidder wins, often because contracts such as this are written by teacher/administrator types, the "goal" of the contract is what needs meeting, with no specifics exactly how to do it... sort of a "design build" deal.Gutting the Davis Dimmer and chunking it is the ultimate goal. It takes up vital wing space and is nothing more than a redundant circuit breaker. There is no use for it and it amazes me that Lehigh did not remove it when they installed their equipment. But as a public school, I'm sure the contracted job was lowballed and removing the old equipment was priced out of the project.
Some similar photos from my archive. At the time these were taken circa 2008, the system was woefully antiquated and beyond reasonable repair. Sliders were worn out, handles broken off, students would stick pens or the occasional screwdriver (!) in to work around that. It was a grossly dangerous system by that point. The portable pack was hauled off to the dark underground tunnel of the school and left in some corner. The wall-mounted panel was turned into a junction box for branch circuit wiring and a Unison dimmer rack was installed next to it and fed into that junction panel to transition the rest of the branch circuits.
Nowadays even that wouldn't be worth the expense. Best course of action is gut it, put in a relay panelboard, and upgrade to LED's. If anyone must hold onto their tungsten fixtures, a modern dimmer rack will do instead, but that's a lot of money to pigeon-hole yourself into being stuck with tungsten dimming and I suspect the cost of putting in a Sensor 3 PowerThru system is roughly the same cost of putting in a relay panelboard with some LED fixtures and a little DMX infrastructure (wireless, if need be).
For that matter, putting in a standard non-relay panelboard and getting wireless Colorsource relays with new LED fixtures would likely be more economical than a PowerThru system for current dimming and future relay capability. Not ideal, but much safer if you absolutely can't get more funding than that.

Since it's not a theater and was in a gymnasium, not sure if code issues would be a problem, but imagine a large supply of orange extension cords built up over time. Sone missing ground pins, some with damaged insulation. A complete mismash of 18/3, 16/3, and 14/3 -- probably no 12/3 to be found anywhere.I'm not seeing the problem? At minimum SO cable would be better but durn that stuff is heavy.
