Tonight's update - The Lenco Reference Pt XCIV - LOADSA STUFF!
The 75 has undergone some serious work since the last update. The paint has been stripped for a start and we have filled in some holes along the way. I'm hoping this is going to be the last paint job for this 75. The top plate now sits in a very highly modded plinth of which very careful attention has been paid towards trying to generate the greatest amount of surface area bewteen the opposing surfaces of the plinth and the top plate, ultimately trying to produce the greatest amount of coupling surface area between the surfaces. I'm still in the process of modding the plinth as I think this can be tweaked further, not much, but still I think further gains can be made.
I've been tinkering with the electrics of the 75 and I'm happy to report that I've managed to dump even more components and here they are :-

The whole idea of dumping components may seem strange. My logic is quite simple in that minimising interfacing surfaces, and components capable of transmitting EMI/RFI and vibration should hopefully lead to better deck performance (the jury is still out)!!!!!
The 75 really has been modded to within an inch of it's life. The bearing received several upgrades. Firstly the ball bearing was replaced was an uprated jobby to handle the additional weight of the new platter mat and dual the double heavy platters. The thrust plte was replaced with something that wouldn't warp under heavy loads and the oil was changed. The platters now spin for stupid long times.

Now for something skin deep. The 75 received some new motor springs courtesy of Sien over on LH. I've also purchased a non-magnetic platter mat which I'm still assessing.

And now for some details on things that you don't see. I've been paying very close attention to detail. The isolation plinth has now been properly levelled out. The 75 has also received new mounting threads, washers and nuts. The top-plate now sits flush to the plinth, something which didn't quite happen last time. I can now achieve greater amounts of coupling using a high powered drill with appropriate socket set . The tonearm is now fully coupled to the top plate without the need of several mounting bolts and all the associated gubbins. The new tonearm coupling design allows assessment of new woods for the tonearm mount with minimal effort so this should extend experimentation for a little longer.
The motor is still a little noisy and need some work and I think I'll need to spend another week or two tweaking the deck before I'm happy to start assessment of all the new mods. Should be quite interesting.
As ever stay tuned and see you at some point in the future.....
