I've got 3 main systems. I thought I'd start this blog to detail my journey. So, this is my 1210. It's very heavily modded and well documented elsewhere on the net. I decided I'd upgrade the isolation board I'm using.   Four simple spikes at a cost of £18, what a massive difference, expect a review soon. |

I have a Lenco 75 which is extremely heavily modified. I can post a link to its evolution if you like. I have a very heavily modifed Technics 1210, again I can post a link to it's evolution. Finally, a Garrard 301 which I salvaged from a garage and completely rebuilt. Again I can supply a link. I will post more info tonight when I have a little time.

Plinth feet - Now fully sit flush to plinth and properly coupled to plinth
* Additional rubber feet under sorbothane footers.
Plinth threads - Now have bespoke 3mm depth / 25mm diameter sorbothane washers to improve vibration supression and plinth coupling
- Mounting washers have been replaced from 10mm to 25mm to work with bespoke sorbothane washers in a bid to improve coupling
and vibration supression over a larger surface area.
- Are now maximally screwed into place into the top plate mounts.
* Wingnuts replaced with M4 nuts which are now improve top plate coupling.
* Original birchply replaced with upgraded spiked feet.
Cartridge - Cartridge pins cleaned and polished.
* Shure M55E original stylus removed for JICO neo SAS N55E replacement.

Idler Arm - Completely stripped, polished and ultrasonically cleaned.
- Idler wheel and idler arm rubber mount removed and freshly lubricated with vaseline
- Idler wheel newly oiled.
- Idler wheel oscillation fixed with Werner stability mod added.
- Idler arm slider fixed - Now not slack and not rattling.

- Mike New Copper/Aluminium Have you considered Mike New's ETP platter? I found it a considerable upgrade over the aluminium one and it operates best with no mat. |

- Mike New Copper/Aluminium Have you considered Mike New's ETP platter? I found it a considerable upgrade over the aluminium one and it operates best with no mat. Yes I tried one years ago and decided that the outlay was not worth the sonic improvements that it provided. I've since surpassed what I heard all those years ago by spending <£100 on the isolation plinth I use and the Crystal Analouge mat. |
