Lenco

I thought I’d treat you all to a pic of a Lenco I built for a good friend. He’s had enough of the UK and going back home so I’ve bought all the kit he couldn’t take with him. This isn’t the best looker I’ve built but I think it’s the best performer.

Nice. Just took my L70 out of rotation. I love the ultra simple bet very functional tonearm cue-on off switch combo. Hard to beat a good quiet running idler.

I LOVE my L70.....stock arm is so cool and functional.

I've run Denon DL103, Shure SC35C and Audio Technica AT3600L cartidges.

Can't get overhang and offset angle set perfectly due to the fixed mounting position in the headshell but using a cartridge with conical stylus minimizes the audible impact.

This is a table that is sooooo easy to use - just beckons you to play music. :)

It isn't in my rotation now but it's never far away. ;)

As always.....YMMV. :)

Thanks all. This Lenco started life as a GL69. The light pressed platter and bearing were ditched in favour of a GL75 bearing and heavy platter. The chassis was turned 90 degrees to allow the arm to mount on the plinth. This deck is unusual in that the bearing mounts directly into the plinth, the top plate only carries the motor and idler/speed change. The top plate is not solid mounted to the plinth, there are compliant mountings to try and keep noise from the motor etc from the bearing.

I built the 12 inch arm using the bearing housing from an old Jelco. The headshell was made by hand and the SME sliding base provides the necessary adjustment.

I did a light to heavy conversion. I used a similar machine belt as yours, mounted below the platter rim. Its a nice finish.

Gorgeous work! I really like the way you crafted the arm. :)

It was made originally for the Thorens TD160 though it would fit many other Thorens tables. I put it on the Lenco platter mainly for aesthetic reasons but it does offer a helping hand to damp the lively platter. A GL78 mat finishes the job off nicely and is the best mat I've ever used on quite a few tables.

Thank you. The LAD tone arm was made by Jelco and I had two of these in poor condition so I decided to rebuild them into 12 inch arms. This arm has a solid brass counterweight with the original Jelco insert bonded into it so it's still decoupled and keeps the original course screw thread. I machined an aluminium bush that was a tight fit on the Jelco pillar and a nice fit in the SME slider to marry the two together. Machining slots in the headshell is hard work for me and I like the versatility of a sliding base anyway. One of the bolt holes in the headshell is slightly larger so the cartridge can be swivelled slightly to aid set up. I made the aluminium spacer too.
I must admit I get a lot of pleasure making stuff like this and even more when I listen to it

Incredible work, incredible result!

I would love to be able to do fine, detailed work like that.

Thank you both! I don't often post my diy work. The response here has been great so I will post some more at a later date if that's ok.

Very nice bearing. Much better than the cir-clip retained thrust pad on the original. What lubricant have you settled on ? I think I might try some heavy oil for tone arm cue descent rate in mine next. Last cleaning I tried out machine oil but I do get the teeniest bit of bearing noise with it. Lithium grease was quiet when I used that.
