I bought an HP3582A many years ago as I was just getting started building my console. I didn't have enough experience to use it when I got it. It has been sitting on a shelf ever since. I'm doing a spring cleaning and selling stuff I don't need and will never use.

The input section looks like it needs calibration or repair as the overload light comes on at power up. I'm wondering if I should put the time in to repairing it and learning it? Does anyone have any experience with this unit? Besides button per function which I love, does it offer any advantages to a sound card/REW setup? These still go for a decent amount of money on the bay. I'm wondering if I should sell it or try to use it?

It looks like a pretty cool box, probably worth investing some time in it. I have a few HP boxes that I have bought in non working condition, and got them going. I have a high resistance meter which is great for testing mike capsules and other high impedance stuff. It had a broken switch shaft on the range switch, that was the only fault. You will need the manual though.

The HP3582A was a great instrument years ago, however with 25kHz BW and 70dB dynamic range almost any Sound Card will be a better instrument for today's jobs and much smaller.

Seems like I should probably sell it. Since it is good with very low frequencies I thought it might be useful for looking at turntable rumble and tape machine flutter. Those are more curiosities than anything else. I’m not planning on designing turntables or tape machines. I suppose it would be good for checking out currently available roller bearings. Practically it seems like an ear or a stethoscope is close enough.
