True stainless steel is non-magnetic. If it's an alloy it might not be.
Try the magnet test.

The metal is unlikely to be from the bolts, steel bolts arent damaged by alloy cartridge bodies, it's the other way round. It'll just random detritus.
I use A3 stainless bolts on mine, none magnetic.

Oli
Have you considered eutectic stainless steel its non magnetic. if you are feeling flush then try Titanium its is only very slightly magnetic but rather strong and light at the same time

I'll have a look but these arrived today and I'm probably ok. However, I could do with a plastic screwdriver.....any ideas?

If you magnetise an ordinary screwdriver then it will attract any stray ferrous particles, away from the cartridge.

Hi Ollie. Sorry to hear about your Kb know you loved that cart😢 Thanks Martin, I did absolutely love it so it's been a bit like the loss of a family member lol However, it's a chance to try something that's pretty much totally unheard so I'm happy to do it. If it doesn't work out, I'll sell it and get a Goldring Ethos

Seems to be a bit of a Sh#t lately.
First up my cartridge died on the repair table and now my bloody meter for the resistor and capacitor matching has give up the ghost.
Good grief.

Yes mate, I sent it off to get the Vienna upgrades but unfortunately when it got there, it wasnt possible as the left channels coil was partly severed by a piece of stray metal. Rare but it happens I have bought a HA103-SEL from Kilian at Holistic Audio

I thought everyone used non magnetic stainless steel bolts these days and we used to chuck those aluminium horrors away unless it was a Dynavector with inset helicoils (17D series) specifically for the aluminium screws they provided....
Records apparently have or had metal filings embedded into them by the manufacturing process I was told and this metal detritus often collected underneath lower slung MC cartridges. The record label or genre of music didn't matter.

Soft metal - too soft for Linnies like me - stripped threads and inability to torque up tight. Nuts supplied do far more damage to headshells in hands like mine as they're too small compared to the stainless steel types which thenselves aren't quite large enough - nurdled headshell slots are commonplace in Linn and sometimes Rega arms as well.
Then again - you could be sensible with the screwdriver and long nosed pliers although I'd perhaps draw the line at using nylon washers as well..
Don't worry (I know you won't). I'm well aware of my past 'training' and have to gentle down a bit these days when fixing cartridges lol!

In this hobby, if you sit still you've either given up or stopped caring. I honestly believe that. I for one had given up. A combination of injury preventing me from pushing myself and a belief that the gear i had was performing at it's best. Yep, i had bought well and quite shrewedly, but as always in this ever changing world we live in, someone was on hand to show me that actually, there is more to be had. Albeit at a price i could never comprehend. After Tony of Coherent visited, i was left in no uncertain terms that my Neurochrome pre was holding my system back. Hard to admit, harder to rectify i thought. firebottle read my bakeoff thread and suggested we bung a linear power supply into the Neurochrome Preamp (NP) and see what happens. Knowing that Tom Christianen is probably best placed to decide what goes into his preamp (Meanwell SMPS) i really wasn't in any kind of hurry to try this out. After all, if he didnt know how to power it best, who does?! Anyway, i trundled over to LAans today with the NP and the 686, mainly to see whether his Dual Mono 286 was in fact better for the recent surgery it had recieved. Turns out it was. In a comparison with the 686, it did seem to spread out a wider stereo image. Wide enough to splurge on a similar surgery to my own 686? I wasn't sure. I mean, thats likely to be over £150 and in all truth, we coudnt use the same pre for the comparison as the cabling needs prevented it. We decided to throw the LPSU in the NP and see what happened. At Alans, i felt it maybe sounded a wee bit more rounded and textured but i wasn't 100%. I took it home feeling a little "meh" "Ok, it's better" i thought, but i wasn't sure how much. After leaving my system in the listening room for an hour, i decided to put everything back in and have a listen in my own system. Well F#ck me, i didnt expect what happened when i listened to the first track. Hans Theesink & Terry Evans - Down In Mississippi Upon the first foot stomp, i sat up and took notice. "As far back, as i can remember" flew out of Terry's mouth with such feeling, that the hairs stood up on end all over my body. Everywhere. Then the whispering of Hans crept out of nowhere.....it was haunting and suspended in the air, like he had just pushed his face through the middle of the gap in my speakers and disappeared back again. The guitar sounds so vivid and the decay to the slide just seemed to keep going and going into a darkness that exists somewhere in the rear of the soundstage. I thought this must be a fluke. You know, a good recording that just happens to sound good etc. I threw on Aldous Harding - Swell does the Skull. I must admit to not liking this song all that much. I only downloaded it to have some familiar material for jimbo when he visited last. I listened and it began to become clear as to why he likes it so much. I bacame rather entranced by her voice. Track after track just flowed by and bfore i knew it, it was 20:00 and the kids were gonna be off to bed. I hadn't noticed the time. 4 hours had passed from when i played the first track. I havent eaten, had anything to drink or even got up from my seating position. I have sat here completely lost in what i have been hearing. The big thing i noticed was the fluidity. Everything has a pooling semsation. Like i could "get in" to it. Totally mad but i don't know how else to describe it. Secondly, the ambience of the recordings is just magnified and seems to have more room to breathe. Ok, it hasnt quite hit the heights of the Coherent effort but it's not doing the same things that was. Anyway, whatever it is doing, i can only say that i will be replacing all SMPS's in everything i own.

What a result Oli and all from swapping in a LPSU. Amazing upgrade I feel for pennies!
I get that holographic ethereal quality from Aldous on my system and it is like someone has walked into the room in the recording but it is I think it is created by the valves rather than a great PSU?
Fluidity is a good description.
I do need to get over soon and have a listen.
