Re: Garage Loudspeaker Lab
So, besides loudspeakers my other hobby is Radar signal processing. I got the bug after I build one of those MIT Kit radars a few years ago.
There are a TON of parallels to loudspeaker transfer function measurement.

The MIT radar is a fun project to work on with your kids too. It's very easy to build and understand how it functions.
Anyway, my latest bit of gear which I picked up for cheap, is this vintage HP pulse generator. The construction is just amazing. I love the old HP stuff. They just don't make them like this anymore.
Edit: Added the finished repair photos. Replaced the BNC crap with nice Agilent SMA connectors. Cleaned out the garbage dust buildup from the analog boards and magic, pulse looks good again.
