My Brute Force "Bench Supply"

[Demonkleaner]

Just finished this variable low voltage power supply. My problem is my junk box runneth over.
It's first use is to gently power up and bias a 2400W (Ideally) MOSFET Amateur radio amp.
It's actually two supplies that I have bridged via the studs on the front. They're paralleled
for the load test but can be stacked, separated etc. It has a built in DBT. The only things
I purchased were the meters and some misc. hardware. The rest came from hamfests,
swap meets and dumpster diving.

Very nice, what is DBT?

Dim Bulb Tester. There's a 100W bulb that can put into the mains circuit if there's a chance of the
device you're testing could pull a large amount of current. Safety thing. One of the photos shows
it working. The big lens that's lit up is with the output shorted.

Thanks, I know how the bulb principle works but I couldn't decode DBT 🙂
