    3 little sorbothane pads have helped in stopping the microphone effect off the feet into the chassis , i suspect this would work with all the gyro /orbe decks ,

    I am next up once postie turns up with sorbothane, I am very interested to see if they work as I believe the vibration and microphone through the feet and into the chassis is a big issue with the gyro. It may not be so much with an Orbe due to the additional spider which the feet are fitted to and the upper spider having the pylons fitted to, obviously a Michel attempt at fixing the issue.

    I will report back on results once fitted.

    I have an Orbe with the original pylons and i have never noticed any microphony issues to be honest!

    the problem is the gyro uses the suspension to keep the feet on , i read an old review were they complained the feet caused noise to travel into the chassis, and you could hear if the platform was tapped into the chassis ,
    also i was told by a user Aejoker on his gyro if he tapped the chassis he could hear the tap through the speaker , The answer was simple in the end to isolate the small shaft in the split adjuster (upgrade system ) in the Michell pylon , what i did not expect was it works as well with the orbe if you have a split suspension , the older type on the orbe , does not have the feet on the suspension or the new type,
    Michell has decoupled the suspension in the orbe , But not on the Gyro , 3 little pads will help stop 90% , it was there when the springs where is use and still there when the new suspension was added due to the Michell design

    Waiting on a new switch for my table (I have a temporary switch in place) but when that comes in and is replaced and I rebuild the table I am going to give this new tweak a whirl.

    I have a Herbie's Audio Lab Super Black Hole here which I use rarely any more as I just don't listen to digital much at this stage. It is a dual layer mat consisting of a very thin top layer of carbon fibre on top of a similarly thin layer of silicone. Designed specifically to reduce vibration.

    So I've punched out and am ready to go. I also have an original Herbies Grungebuster CD Mat that I've also punched out. It is an extremely thin rubber material with a bit more adhesive on the underside and I may place a piece of that underneath the Black Hole material to prevent it from rotating or slipping underneath the ball bearing.

    Will report back with results when it happens.

    That looks interesting Blake. I guess you are putting these under the bearings on the pylons yeah?....looking forward to hearing about your findings Blake. I'm using the sorbothane provided by Peter and it is very effective..

    Yes, underneath the bearings. That's the plan.

    Makes sense why its not a problem on my Orbe then!
    Well done on yet another verycheap mod which appears to work well

    I just tweaked the Gyrodec again, 8mm diameter by 3mm sorbothane glued to 1mm thick rubber place on the top of each suspension pylon and then the supports for the chassis (the threaded adjusters that the springs are normally on) fitted over them. This is to try and get some form of decoupling of the chassis from the legs which are attached to the pylons through the spider. Also my feet sit on small indented discs, I have glued some 2mm rubber under these as well.

    Listening tests are that initially things sounded a little dry, then after listening to a few tracks I realised what has happened. There is obviously some form of better de-coupling due to the sorbothane/rubber in the pylons, the result is that there is less microphony (feedback) going on through the chassis enhancing and colouring the music. So bass is more defined (less bloom), overall more clarity and separation.

    So a positive result. Not perfect, tapping on the shelf with a record playing still induces a noise through the cartridge, but I would estimate a 50% improvement. The only other thing I can think of is to replace the Gyrodec metal feet with some form of rubber feet, possibly firm sorbothane. I am going to search for some that may be a similar height and could be fitted in some way to the pylons.
