Possible Cartridge Suspension Collapse?

I dunno, it seems like my Hana SH is riding lower and lower as time goes on.

I got it new in 2018 and haven't spun all that many LPs on it - maybe have 350 hours?

Yesterday, I was spinning some LPs after not using it for about 2 months and at the start of every LP, there was a whoosing sound from the speakers - turns out the bottom of the cartridge was making contact with the very outside raised edge of LPs. Then as the record plays it would stop, but the cartridge body is darn near touching the LP surface - I mean practically an "RCH" distance.

On my Technics SL1200mk2, I run my VTF right at 2.0g (double verified with a Shure gauge and an electronic one).

Was thinking of moving up to the Hana ML, but now skittish of Hana's - may have to start thinking of getting a replacement regardless as my SH is just too low.

I was actually considering the ART9XI, but the resonance calcs for my setup put it at just *under* 7Hz.

I was waffling between a Sumiko Songbird LOMC and the Audio Technica AT33SA - and went with the AT.

I grumbled with MD on the measly 20% credit for the bad Hana, but that's all I got.

Once I get everything sorted out and back up, I'll post some listening impressions.

Time to move - thanks for all the input!

Did you convert 100Hz to 10Hz before you made any calculations?

The compliance measured at 100Hz:
15 x 10-6 cm/dyne (100 Hz)

In reality at 10Hz it will be 25.5 cu which is fine for your Technics tonearm!

Yes, yes I did.

Then you should know that AT (ART1000) was Technics official cartridge for a demo of their reference class tonearm and turntable on audio shows.

I had a Dynavector DV20x2L cantilever collapse, t was fairly elderly and I got a discount on a replacement.
