= for Bamboo, did a 301 in it a few years back, excelent if not a pain to work with.
plinth material
Hi All, I have two questions really.
I'm planning on building another Lenco 75 on a PTP5 top plate and am seeking a supplier of phenolic resin impregnated wood here in the US for construction of the plinth. A commonly known brand is Panzerholz.
Secondly, Is there a different material I should consider instead? I have one I previously built out of slate so looking for something different this time.
Thanks

10 mm seems way too thin just from a support perspective to be the only layer of the plinth. If it were a sub-layer what might you consider for the top layer? I have a left over slate piece that's about 18mm thick. My current table has a 3rd bottom "skirt" layer just to obscure the view of the motor. When I was building the current table I saw folks suggesting bamboo cutting boards from IKEA.

The New Linn Plinth is a Resin Impregnated Densified Wood Board, which is most likely CNC Machined to produce the Peripheral Form to support other structures. The method, if done as above leaves quite a large cut out as a wastage, this wastage would have been much better used to produce an update of the Sub Chassis. Two Parts of this material used in conjunction will have had a much improved impact than remaining with a Aluminium Material. Linn's selected board materials has a low number of Plies per 25mm, it looks like they missed this importance, they material is cross grain. I have costed the Raw Material for the Bedroc using the cost I know for other produced materials of the similar design, but with more Tiers per 25mm, resulting in increased costs. The Bedroc as a Blank Material in a Plinth Dimension is approx' £350 per Blank if a full Board is purchased and reduced to Blank Dimensions. Bring on the DIYer and Copyists out for a quick buck |
Hi, I have made it known in past posts, I was a 401 owner and used it as a Massey Plinth Design ( 9 Stone Granite ), I sold the TT who a friend who was also a Lenco TT person of which I was and do still own a Lenco as a PTP Design. During visits to my friends I have heard Plinth designs used with the Garrard 401 that easily surpass the Granite Plinth where tidying up the End Sound is a concern. I have also been introduced to Lenco Plinths using a non PTP Lenco that easily match/surpass a PTP design Lenco. I have not been demo’d a PTP design Lenco in a friends design for a Plinth?? Maybe / Maybe not a good impression is to be made. With these experiences had, where Plinths are built using techniques similar to the designs used for expensive Plinths that are built and sold by those with a commercial interest in producing Plinth designs for Idler Drives, I was off the view the non Mass Plinth, or especially a move away from my earliest Mass Plinth method was the way to go. The above thoughts were to change very quickly after a demo’ of a 401 another friend purchased, which I refer to in an above post. The Plinth design for this 401 was a Single Board of Thin Veneer Bamboo Plies, stacked as a Cross Grain Orientation to produce a Board of 25mm Thick. The board was produced as a Highly Compressed Top Force / Side Force Applied Bamboo Board @ 1000Kg/m3. I strongly recommend this as a consideration with a couple of Sub Plinth Tiers made from the same material. I also strongly suggest that further can be attained if the Bearing Housing at its lowest point was to be rigidly locked of from being effected by pendulum occurring when the TT’s chassis is flexing. The owner of the TTS 8000 referred to below carried out a version of this under guidance and got end results not foreseen. Additionally, I strongly suggest that further good impression can be attained if a material being selected is a ’Resin Impregnated Densified Wood Board’. On either type of Material used as Plinth, a Skirt can be added to mask the Mechanics, that will be visible when a Board Only design is selected. The Skirt can be produced from any material or a Veneered finished material. The Plinth Board can also be aesthetically changed by use of a Veneer as well. ( A search on Google for a TTS 8000 with a Panzerholz Plinth will show images to give an idea.) Footers/Separators/Isolators are required, on Sub Plinths I have got my best results from a pneumatic design. With all that I have done as investigative work into Isolation methods, and what I know today, the items shown in the link or equivalents, do seem to offer a great place to start at very very fair monies. The footer used directly under the TT’s Plinth has been superseded in my system and I use Feet of Silence, but again prior to considering spending such monies on a product of this type, the design in the link really does look to have a lot to offer. Versions of this design in the audio world from certain brands are seen with 15 x increased in value asking prices. The Footer in the Link has a Race Track Shaped recess which can be used to house a ellipse shape cone bespoke produced for the same material used for the Plinth? Little things such as this can be used to attenuate a sound, as the interface produced do impact on the fine tuning of the balance of the coherence of sound influenced by mechanical energies being present. Nantais was very vociferous in how they included substances embedded in their plinth designs to fine tune sound and create alternate presentations, with that in mind, a selection of materials could be used either on top of or under a footer to tune the End Sound to ones personal preference. Much is stated about mechanical interface materials, which now leaves the ID TT and the importance of changes made to the OEM Speed Control. A ID TT leaps forward in good impression made when Speed Control is in the hands of a purpose produced design for the role. I own a device and have heard a selection of devices in use, even side by side in comparison. The LDA Speed Control is the most impressive design I have been demo’d and have compared this model to others where it has shown its qualities and been selected by a group as the best option. .https://www.longdogaudio.com/product/lda-quartz-turntable-power-supply-mkii/ If an individual is able to source the materials as a board only and have the board produced as a Plinth, this route leaves quite a bit of spare funds to consider where the design for the TT can be taken. Everything suggests the use of 3D Printer Anti Vibration Support design lends themselves perfectly to audio, especially when a Hockey Puck, Squash Ball or Rubber Pads are claimed to be so beneficial. Selecting 3D designs and side stepping branded designs aimed at audio usage, will also assist with retaining substantial monies that can be used to further address where the TT’s end design can be taken.
