Is this FFT analyzer still of any use? I can get one at a bargain price, although with blown inputs.
Perhaps a decent soundcard and a PC with FFT software is better. Opinions?

From what I have seen, Ono-Sokki analysers are typically intended for vibration measurement. You may well be able to use it for audio measurement, but I suspect you will find it's more geared towards acoustics and industrial testing, such as looking for modes that indicate worn bearings on crankshafts and the like. I passed on one recently at £150 GBP (approx $180 USD), as it was a large and heavy beast and I knew in my heart that it would take up a lot of space, but get far less use than any other analyser that I have.
Along with several other AAs, I have a Prism DScope. On loopback, the THD+N from the 20+ yr old DScope is around the same as a MOTU M4 soundcard @ $250 USD... The only real advantage to the DScope is its inherent calibration and auto-ranging. It cost around $10K USD when it was new! So, in answer to your question, unless you have a fetish for CRT displays (I confess, I do), choose life and get a soundcard.
NB - have you checked the noise level from the Ono-Sokki's fans? Is it quiet...? And those blown inputs... What price do you put on your time to fix them?
(it could be something simple such as bulbs to protect inputs...but do you feel lucky?)

Used a Ono Sokki 350 and a 360 for some time .... liked it. Useable dynamic range is about 80+dB.
Used both for many years. The 350 goes up to 40KHz, the 360 to 100KHz and has a build in Generator.
Replaced it with an R&S UPL. But the 350 is still in use and works flawless.
See attached a measurement with the 360 on a low distortion audiogenerator ... -80dB distortion nice and clear to see ...
Best regards
