Tonights Update - The Reference Lenco Pt XXXXV - Tyre Kickin', or waiting for your fettled tonearm.
The old Alphason has been gone two weeks this coming Friday so I decided to finish a few little jobs. I managed to get my old Celestion Ditton 15's reworked and then I decided to take a little time to further mod the '75. Tonights pictures show you all what I've been upto. The first picture shows the new silver umbilical power lead which goes from the Nigels Speed Controller to the Lenco's motor. The old power cable is now sitting in my spare cable box in the attic. The final cable is the old Lenco switch. Originally I wanted rid of this but after speaker to a few people it would seem prudent to leave it in place. So I'll be shortening the cable which should smarten up the underside of the '75.

A quick picture showing the back of the deck and the speed controller.

Now this pictures demonstrates an extremely expensive component from China, the ferrite coil! I picked up a pack of 10 for £2.79 delivered from China!!! :eek:The Lenco now has 4 in situ, two which sit under the platter and hopefully prevent any crap getting into the Lenco motor and a couple sit just before the Nigels Speed Controller. It will be difficult to assess if they help but at less than £1 for 4 it can't hurt! I've added them because I noticed quite a difference when I employed them on my Technics 1210 and associated kit.

More attention to coupling and dampening. I've replaced the 4 wing nuts which I used at the end of the top plate mounting rods with 4 simple M4 nuts. I found that I was getting more of the top plate to couple with the plinth when using thse and especially when they were tightened with the molegrips. The plinths feet are now sitting 100% flush to the plinth whilst previously one the feet didn't quite make it, so, coupling of the plinth to the IKEA chopping board should be improved. The dynamat was found lurking at the bottom of my spare cable box so I'm going to see where it can be used to dampen vibration. I'll probably end up putting this in discrete areas around the motor and maybe the bearing. We shall see, be assured I'll post some pictures.

I'll be paying more attention to the coupling of the tonearm. I dont really want to undo the deck again for some time. I'd like to listen to some vinyl at some stage! So we still have a little way to go before we are fully finished. I may even decided at some point to de-couple the motor. I'm in the process of looking at the various solutions that have been proposed over the years. I have my spare motor and top plate out on in workshop and when I get a little time shall start experimenting with solutions. :popcorn:
I've enjoyed putting tonights update together.
Well, as ever please stay tuned but until then..... :wave:
