Thanks for this guide. My arm was skating like mad and it turned out that one of my v-blocks was badly disintegrated. My Great Uncle gave me the turntable a couple of months ago and I've just started getting it back into shape. I've ordered replacements but I'm going to have to get the remains of the right hand block out of the fixing hole - it literally crumbled to pieces!
This place is an absolute goldmine and I'm so grateful it exists. Don't tell my other half but I'm tempted to make a new platter. Babysteps first though!

You're welcome Grumpius.  Your great uncle is a good man. Make sure to invite him over when the Lenco is properly renovated for a few of his favourite tunes and perhaps a beverage or two. Be prepared that he might want his Lenco back though.  I'm curious about your plans for the platter. Is it damaged? What are you thinking of doing? |

The platter is sound, albeit with a little bit of corrosion on the outer rim that rubs with the top plate. I've sanded most of it off and the problem has reduced enormously. I could do with a little more work on the platter but it's sound. I've just got my new stylus in the post this afternoon (after a day of training for work in London).
Ultimately I want to make a new plinth (and I've got a few ideas for a self-levelling design) but the main issue I have is a lack of space. I live in a one-bedroom flat and I have a lot of audio gear so I need to clear a dedicated, decoupled space for the Lenco. I'm tempted to go for a minimal (but heavy) plinth but it's going to be a long time before that's possible. I'm totally new to Lenco and vintage turntables and although I'm decent at setting up modern systems (I have a direct-drive Citronic) this requires a bit more tweaking. It'll be worth it.
Unfortunately budget is my main constraint so I can't afford a moving-coil cartridge and instead have had to go for an Ortofon OM5E - which I've used before and had decent results with - so my upgrade order is:
i) Install new V-Blocks
ii) Install and set up new stylus/cartridge/headshell as well as sort out the minor platter issue
iii) Enjoy
iv) Upgrade cartridge (this will take a long time to save up the money, if I can)
v) Build plinth. I was thinking of using ball bearings for controlling the tonearm (to replace V-Blocks, etc.) and a gimballed/compact/heavy design but goodness knows if that's even possible!
As for my Great Uncle - I'll see but it's very much a case of me going to see them rather than coming to me! Tricky for them to visit and my flat isn't the most hospitable for guests (it's tidy, just not very nice!).
What would you recommend as an upgrade path?

Not sure that this has any business in a Lenco Guide?

What a superb guide. I will be using it this weekend as i intend to replace my V blocks with some Desmo blocks.
Can anyone inform me if the V blocks affect the anti skating if they are worn and have they notice in improvement in SQ with the Desmo blocks?

Don't know about the anti skate James but changing the v blocks certainly improves the SQ .
Nice guide BTW . Thanks chaps .

Hello everybody, This is a nice forum I have one question: Does these v-blocks fit in the B52 MKIII as well? Best regards! /Olle |

Just disassembled my new (to me) Leak Delta and discovered that my V blocks are indeed toast! Speaking as someone who writes instruction manuals for a living, these instructions are pretty damned excellent Thanks. Now awaiting some new V blocks... |

Yeah, L75 type arm and the square block arm used in B52 are similar in most aprts. The only difference is defferently shaped arm pillar (plus counterweight and lack of wtf weight). Both vertical bearings (V blocks) and horizontal bearing are similar in both types of arms. |

Yes, althought it might be that the earlier versions didn't have v-blocks at all (not sure). |

Mine is dark gray chassis without separate arm-rest and without anti-scating - looks like Mk2.
I would like to remove the arms pivot assembly but not able to.

See ropie's post, the last one on the first page of this thread.
The tonearm cover may be very tight. I only got mine off by spraying some deoxit under it (to lubricate it a little without actually oiling it completely) and then levering it towards the front end of the arm with a small screwdriver.

Thanks for the advise. I got it off finally. It was very very tight indeed. I put rubber cloves on and rested my thumbs on the side of the arm and tried to slide the cover with fingers towards my thumbs. It took some effort.
So mine has no V-blocks. But the grooves were full of dust, otherwise in exellent shape. While the arm off I fixed the grumbled-off white rubber button that supports the arm on the up-lift with a new one I has off another cheap arm.
I don't think I need any lubrication for the V as much I understand the mechanics of it.
