Hi there my dad just bought me this ......device, which we had no idea what it was. Ive been playing around with it and i believe its an old fashioned benchtop power supply.

The switches on top have effect on voltage, but the labels are incorrect by couple volts or so.
The knob in middle (Not the needle, that isnt electronic it just spins lose) has 3 points which i connected ammeter and change from off to 0amps to 0.11 amps to 16+amps.

The buttons below i've got no clue what they are.

Just wondering if anyone can clarify what this device is and if possible guidelines on how to use it.

thank-you

It's a lot of cool parts.

It's a flux capacitor. You can go back in time with it, but you need 1.21 gigawatts.

From the TV show "Lost". This must be the thing that made him so fat.

ooooohhh soo thats what it is....hahah

attached are some of the pictures of inside the unit.

2 transformers inside, with multitap windings. no ic's seem to be present.

It's a student project LCR bridge with a built in wein bridge sine oscillator. I have a very similar one here but less options on it, mine is one a student didn't pick up at the end of their electronics course, it's from the mid '70s. The students have to put their names on them.

Your unit seems to be Aussie made too. The label/dial on that one looks similar to mine, it has been photgraphically developed probably using the same classroom equipment as used to make circuit boards.

The knob in the middle should be a pot, and the pointer line should be glued to the pot.

Funny mine has a little peaking panel meter used to detect the resonance (ie when testing LCR) does that one have just a LED??

I've got a bad feeling that yours has been butchered, the 2 transformers bit does not seem right, neither does the 240v mains receptacle on the rear, and if the main pot has been replaced with a 3 position rotary switch than the whole thing might just have been "converted" to be something crude like a DC power supply.

If it still has the wein oscillator there will probably be a tiny "grain of wheat" light bulb inside in the oscillator section.

There's a couple of jacks for a meter on the left there, maybe that's where the peaking meter goes. Sounds like you have the best guess so far. If spitso doesn't have a scope, could he at least get the wein bridge oscillator to beep a speaker?
