Krohn-Hite model 7500 amplifier

We (our local ham repeater club that is) got this as a donation.
Seems to work fine, save for some dust that smelled funny
during amplifier powerup.

Now what to do with it?  :-//

Use it as the line driving stage for a laser based video display?

The thought... /me wanders to the garage to look at my stash of HeNe laser tubes..

I certainly wouldn't mind having such a an amplifier laying around, it allows you to basically power anything you want with a signal generator.

You can use it to generate weird mains frequency supplies like 16.6Hz 50Hz 60Hz 400Hz, simulate harmonic distortion on AC power, drive anything with a voice coil from a speaker to galvos. Can make a AM radio transmitter out of it. Can be used as noise injection into DC rails or into metal cases to see if a device is robust to interference. Could probably also drive some piezzo elements for ultrasonic things or sonar...etc
