RIP illegal power supply |

No more illegal power supply at the LSC rack 
The amplifiers are now being powered by the rack power supply through fuse blocks.
To make new connections, I shutdown the +/-15 V low noise power supplies. They were turned back ON after the work.

Is this your illegally installed HP bench power supply?
If so, or if not but you care about the signal that passes through these amplifiers, I suggest you remove this temporary power supply and wire the power from the rack power supplies through the fuse blocks and possibly use a voltage regulator.
In 24 hours, that power supply will be disconnected and the wires snipped if they are still there.
