I seem to remember doing this around 30 years ago with my Philips Hifi VHS recorder when we were thinking about the possibility of using it for recording 30kHz sonar at work. My memory is fairly hazy but I seem to remember the -3dB point being around 30kHz with usable output up to around 50kHz and a very small signal still there at around 90kHz. It must have been sufficiently impressive as the people doing the project bought themselves an Akai machine (my Philips was long discontinued).
It was only superceded when 96kHz sampling rate digital audio recording came along.
