I finally bought an IR camera, only $219 on eBay:
VEVOR Thermal Imaging Camera, 240x180 IR Resolution (43200 Pixels), 20Hz Refresh Rate Infrared Camera with -4℉~662℉ Temperature Range, 16G Built-in SD Card, and Rechargeable Li-ion Battery

Marco Reps does a good review with a teardown here: https://youtu.be/3oltoOSAziU
I have a broken Carvin EM900 (in-ear monitor transmitter)--something is drawing current and preventing it from booting up. The camera quickly identified trouble spots.
There was a 5v regulator in one of the hot spots--it measured shorted between GND and vIN, so I removed it with my soldering iron, and destroyed the solder pads! I am NOT set up for SMD work. Anyway, the regulator measured OK OUT of circuit, so whatever.
The camera is also useful for colorful pet photos:

That's one relatively cool cat. Nice.
Just plug it in, man.

Re: IR cameras are cheap enough that I jumped in
Only complaints so far: 1. It takes ~30 seconds to boot up. 2. I got the less expensive version, with no visible-light camera, so no combined images for me (no big deal for tube amps, because the components are large, but it would be very valuable for SMD components).

Here is a 50-watt L-pad in action, at max attenuation, playing full gain thru my 4-watt Black Butte Desktop #4. No matter how hard I played, I couldn't get the temp over 160°F, and it cools rapidly.

Re: IR cameras are cheap enough that I jumped in
I picked up a FLIR a few years ago and always had trouble with differentiating smaller components. Turns out laser cutter lenses are clear to IR, relatively cheap, and come in useful focal lengths. Got a $40 GaAs lens in the mail a few days ago to use as a macro lens, but haven't figured out how I want to mount it yet. Hopefully this will make identifying SMD stuff easier. I don't have the visible light overlay thing either...
