I've been offered all this for a few dollars.

I personally probably couldn't use anything else than the power supplies and voltage regulators, but I honestly have no idea what the rest of this stuff is/does. The guy in charge of liquidation told me I could have it for cheap and I have already bought their network equipment for a few dollars each server/Firewall/etc since this is exactly what I needed for a new office/server room. He mentioned $150 for each unit, but I am sure I can get him down to 1/3 of that since I don't think many people are interested in any of this. I am not looking into reselling, unless someone here convinces me it's something they really want/need and I can safely ship it from here in Hong Kong to wherever you are (will be a nightmare and costly but doable).

Does anybody recognize anything here?

Seems they were in the business of developing some kind of AM/FM stuff, but some of the equipment looks useful (Oscilloscope, power supplies, etc).

Anyway, here is the album link with more photos and other equipment:

Here's my basic analysis of the photos:

Photo 4 - Dual channel oscilloscope, used to look at waveforms of electrical signals, image is kinda hard to read but it looks like 100MHz, worth approx $100
Photo 5 - Adjustable DC power supply, 0-18v 0-3A, worth approx $50
Photo 6 - Appears to be some kind of signal generator, pic is too blurry
Photo 9 - AC Voltage regulator, removes noise and regulates mains voltage, 1KVA, worth approx $50
Photo 10 - 2 channel frequency counter, tells you the frequency of an input signal, worth about $30
Photo 11 - Square/sine wave generator, used for testing equipment by generating a known signal, worth about $20
Photo 12- Distortion Meter, used to measure distortion of a source waveform after going through a piece of equipment like an amplifier, worth about $150
Photo 13 - 2 channel AC Voltmeter, worth about $20
Photo 14 - "CD player evaluating filter" no real idea on this one
Photo 15 - Looks like a nice signal generator, output likely in the radio frequency spectrum, rough guess is maybe $200 or so

Hope that info is helpful, most of those prices are on the optimistic side, and assuming that all equipment is clean and fully working

Assuming it is working, I am interested in this.

Don't mix your coins someone said isn't legal

Wow, that's valuable info right there. I just thought some of the equipment might be expensive (ie. north of US$ 10k) because the liquidator mentioned it. But with these prices it definitely doesn't make sense buying or shipping any of these.

Definitely not worth shipping around the world with this value Kluge, the shipping cost for a heavy brick like this will be more than the value of it. I might just take it for me, because I can pick it up with my network gear. I've already put a laboratory power supply on the side, it's not in the photos.

I hoped there might be one or two pieces that make somebody drool here (we all heard of the $4000 FPGA dev board that went on eBay for a few bucks), then shipping would have made sense.
