Hi Kravi4ka,
Congratulations on your excellent arm purchase. I am sure
that you will have years of enjoyment out of this beauty.
Yes, overhang is 19.6 mm, but you can also experiment. I
position the arm basically like JNantais does in his setups. Except that I may be positioned a little higher vertically as I use a round 3-4 mm rubber spacer under the base of the arm to keep it steady. I don't place the arm on the metal part of the Lenco. I rotated the table (like in JN's pictures)and place the arm on the plinth proper. See JN's Bauhaus Lenco. I did not make a separate arm cutout though, so the arm will rest on laqured MDF. I have some quarter inch bubunga hardwood to make an arm platform and an aluminum one as well as a pink ivory piece. I will experiment as to the best sounding one and laminate it on the plinth. I have a higher platform probably because the Shelter 501 is a taller cartridge. VTF is adjusted with a hex key at the base of the tonearm. Be careful when adjusting because the arm gets excited when things get set in motion and it does'nt take much to get the counterweight swinging and then the arm as it rests on the cup to swing.
Also,always remember that those little tonearm leads are what holds the whole contraption together, just don't force
them to support the weight of the arm by dangling one part. Always use two hands when you handle the arm. I like to grasp from on top at the bearing the armand base together
while supporting the bottom of the base with other hand.
I don't have a digital camera to post a picture. Sorry. I tried the arm with a factory modified benz silver before my 501 and it played better than when it was on a modified Rega. I have an OC 9 and a Rega Elys kicking around but ever since I mounted the 501 I have not bothered to hear these on the RS labs. As to polishing the cup, I have not done anything to mine. For set up info, I have the original papers included in the box, and basically they are the same as the Sakura info. On their website,look for the diagram
of thearm as seen from the top riding in an arc accross the record. Follow that at 19.6 underhang and your in business. The junction box that I had removed from the arm and wired direct was suggested by the designer of the arm
in Japan. I had requested from Yoshi the Sakura head guy a full four foot long arm lead to go directly to the pre.
He called the arms designer to order but he cannot supply that length. As an alternative he recomended to try the mod.After about 2 hours of breaking in it already sounds much more open and direct. Very very worth the effort and cost to do.
Start playing the arm and experiment with VTA, underhang,VTF to your hearts content. You will discover a whole new world of flexibility. For me it was my greatest upgrade. Well that and the Lenco that beat my Linn/Lingo which I am still trying to sell. Enjoy Kravi4ka.
