这是我使用了近半年的转盘:Well Tempered Classic,因为用户不多,因此在调整时只能自我摸索,带来很多困扰。
前几日得到Review33上网友的热心相助提供Well Tempered Record的装配说明和阻尼计算两份文件,虽然是Classic的下一级产品的说明书但还是给我莫大的帮助。
特意翻译过来贴在这里,供有需要的朋友参考,我的翻译很菜,担心闹了笑话或误导别人,因此后面会附上英文原文。

Well Tempered Record转盘装配
重要事项:唱臂组合非常精密脆弱,在安装唱臂前清仔细雨度和遵守使用说明。
你需要以下工具:
微型螺丝起子
微型长鼻钳
转盘附带的Well Tempered Lab转盘量角器
精确的针压计
转盘附带的3/32" Allen扳手
1、安置转盘在平坦水平的表面,马达组合洞在你面对转盘的左边。
2、使用发泡水平尺调整转盘水平,少量水平调整可以通过旋转盘底的橡胶垫脚完成。
3、在转盘基座中央的轴承杯内注入轴承油,大约满至轴承杯的5/8。放置不锈钢轴承在杯中并确认轴承到达杯底,适当调整油的高度使阿承放入时覆盖至杯顶。注意:转盘轴承油是稀的而唱臂轴油很稠。
4、小心地在唱盘基座的轴套上移动唱臂柱,避免压迫两条悬挂唱臂的细线。使用附带的内六角螺丝刀轻轻拧紧固定螺丝(从唱盘基座右边的透孔可以操作)。
5、在唱臂杯中注入唱臂油,唱臂油注射器在唱臂盒底部,使用螺丝起子手柄来推活塞注入唱臂油,唱臂油非常稠,当它沉淀后,应该要覆盖白色的臂砣1~2mm。
6、将唱臂搁架挤压入唱盘基座的洞内,放一块折迭手帕在其顶部以免撞到手。完全固定之前摆正上的开槽方向以放置唱臂。
7、使用附带的螺丝安装转盘背部的接线柱挡板。
8、电源线从马达洞底部引出至转盘背面。放马达组合入洞时让电源开关靠近基座左边,并且不能接触基座。
9、在轴承上放置亚克力转盘。
10、在转盘和马达滑轮之间安装皮带,在靠近滑轮的地方将皮带反转半圈,可以令皮带在离开转盘接近滑轮时转得更平滑。
11、在唱头盖下安装唱头,用手指抬起唱头盖,也可以使用你的唱头附带的螺丝。小心安装镀金的唱头线夹避免损坏线夹或唱臂线。
12、安置唱臂:
A、将量角器置于轴上
B、松开固定螺丝这样唱臂组合就可以轻易地在原处旋转,当拖住唱臂的时候(不要旋转唱臂杯来转动唱臂),转动唱臂到唱针针尖超过转盘轴心的位置,针尖与量角器上画的圆圈排列。
C、这时通过滑动垂直的活动唱臂柱来初步调整VTA。这时可能要求松开固定螺丝升降唱臂然后轻轻紧固螺丝来暂时固定唱臂。小心不要旋转唱臂组合从而改变超距值。可以用铅笔划一个小的参考标记在唱臂柱上来保持原设定的超距。
13、通过移动唱臂的重锤进行初步的针压调整。确认臂砣充分稳定并且不接触唱臂杯边缘。测量针压时有必要将唱针置于唱片等高在或接近等高。
14、使用量角器调整唱头循轨偏角。调整螺母在唱头盖洞内的位置令唱头旋转,然后旋转转盘令唱针与两个交点交汇,使唱针落于两个交点时唱头平行于量角器上的直线。
15、放一张唱片在转盘上并拧紧唱片镇。调整唱头方位角让唱头前方底部与唱片表面平行,可观察唱头在唱片表面的倒影。因为唱盘表面的角度问题,方位角必须在拧紧唱片镇后进行。
16、调整VTA
A、松开轴套的固定螺丝垂直调整唱臂,直到从唱头侧边观察平行于唱片表面。使用参考记号标记正确的超距。
B、拧紧螺丝固定相应的VTA位置。
17、次检查方位角,不要弄错。
18、再次测量针压。重要提醒:浸在在稠油中的臂砣在最后的调整进行之前必须有充分的时间来达到平衡。每次移动重锤后臂砣会移动少许,这样在臂砣稳定后再次检测针压是必然的。
19、从唱臂杯中增添和减少少许稠油,或者调整拉悬的细线,阻尼的数值会随之而改变。一条细线被唱臂柱末端的螺丝紧固,另一条细线被方位角旋钮控制。阻尼上小小的改变会带来声音上的大变化。如果你改变细线的位置,必须重新调整VTA。
20、使用注意事项:
A、如果速度不均匀,检查滑轮、转盘边缘和皮带上是否沾上轴承油。如果有必要用酒精擦干净滑轮、皮带和转盘边缘。
B、轴承底部尖端的特氟隆螺丝固定密封,无法进行非破坏性调整。
C、最适宜的抗侧滑力被设计在唱臂中不需要调整。
D、唱片镇稳固地拧紧但是不要过紧而减小了唱片外部边缘的向下压力。
E、从一处移动WTT转盘至另一处时最好移去马达,同时保持转盘状态在一个水平的表面上。放一块软布料在转盘和地盘之间以防止转盘晃动,如果有必要可以将硅油抽出来另置,可用软布沾酒精擦拭清洁。

因为是木地板,特意定做了15CM厚的花岗岩用以避震,效果还不错。
下面是厂方的Record转盘说明书原文:
SETTING UP THE WELL TEMPERED RECORD PLAYER
IMPORTANT: Arm assembly is delicate. Please read and observe instructions before installing arm.
You will need the following tools:
miniature screwdriver
miniature long-nosed pliers
Well Tempered Lab protractor supplied with table
an accurate stylus pressure gauge
3/32" Allen wrench supplied with table
1. Position table base on flat and level surface so that motor assembly hole is on the left as you face the turntable.
2. Level table base. Use bubble level if available. Small amounts of level adjustment can be made with the rubber feet which are threaded into the base.
3. Put table bearing fluid in bearing cup in the center of the base. Cup should be approximately 5/8 full. Place stainless steel spindle in cup making sure bottom of spindle is resting on bottom bearing. Adjust fluid level, if necessary, so that it covers the top set of bearings in cup when spindle is in cup. NOTE: Table bearing fluid is thin and arm bearing fluid is thick.
4. Carefully set main arm post in bushing on table base. Avoid stressing the two lines on which the arm is suspended. Lightly secure set screw (accessible through hole on right edge of base) using supplied hex key.
5. Put arm fluid in arm cup. Arm fluid dispenser is on bottom of arm box. Use a screwdriver handle to push plunger. When fluid settles, white paddle should be covered by 1 to 2 mm of fluid. Fluid for arm is very stiff.
6. Install arm rest by pressing it into hole in base. Place a folded handkerchief over top to protect your hand. Line up slot in arm rest with arm before pushing arm rest all the way in.
7. Install terminal block on back of base with screws supplied.
8. Thread power cord down through motor hole and out to the back of the turntable. Lower motor assembly into hole with switch facing left edge of base. Motor assembly should not touch base.
9. Place acrylic platter over spindle.
10. Put belt around platter and motor pulley. Make a half twist turn in belt at pulley end to smooth belt's peeling off platter as it approaches pulley.
11. Mount cartridge under headshell with fingerlift on top of head shell. If possible, use bolts supplied with your cartridge. Be careful installing the gold cartridge clips to avoid damage to the clips or wires.
12. Position Arm:
a. Place protractor on spindle.
b. Loosen set screw so arm assembly rotates easily yet remains in position. While holding support arm, (do not turn arm by using cup for leverage) turn arm assembly into position until stylus tip extends past the spindle and the stylus lines up with the circle drawn on protractor.
c. Make preliminary VTA (vertical tracking angle) adjustment at this time by sliding arm post vertically in bushing. This may require loosening set screw to raise or lower arm and lightly tightening it again to maintain arm position. Be careful not to rotate assembly thereby changing overhang adjustment. A small reference mark may be made at base of arm post with a pencil so you do not lose the overhang setting.
13. Make preliminary tracking force adjustment by moving counterweight on arm. Make sure paddle in cup is fully settled and is not touching the cup edges. It is necessary for the stylus to be at or near the level of the playing surface of a record when measuring tracking force.
14. Use protractor to adjust angle of cartridge and position bolts in headshell holes so that cartridge is parallel to lines on protractor when stylus is placed at each of the two cross points on the protractor. Rotate platter to line up stylus with each cross point.
15. Place a record on platter and tighten record clamp. Adjust cartridge azimuth so that bottom front of cartridge is parallel with record surface. Observe reflection of cartridge in record surface. Azimuth must be set with clamp screwed down because of angle in platter surface.
16. Adjust VTA.
a. Loosen set screw in bushing and adjust arm vertically until side view of cartridge body is parallel with record surface. Use reference mark as described in 12c to maintain correct overhang.
b. Tighten set screw to secure parallel VTA position.
17. Check azimuth again. Do not over correct.
18. Check tracking force again. IMPORTANT: The tonearm paddle must be given time to reach equilibrium in the tonearm fluid before final adjustment can be made. The paddle will tend to move a little each time the counterweight is moved so it is desirable to recheck tracking force after the paddle has stabilized again.
19. The amount of damping can be changed by adding or removing small amounts of fluid from the cup or by adjusting the suspension lines. One line is secured by a screw at the end of the support arm. The other line is adjusted by turning the azimuth knob. Small changes in damping can make a big difference in the sound. If you change the position of the ines, be sure to readjust the VTA.
NOTES TO USERS OF THE WTRP
a. If speed is uneven make sure pulley, platter edge, and belt are free from finger oils and bearing fluid. Clean pulley, belt, and platter edge with rubbing alcohol if necessary.
b. The teflon set-screws (bearing points) in the bearing body are permanently sealed and can not be adjusted without damaging the bearing.
c. Optimum anti-skating is designed into the arm and is not adjustable.
d. The record clamp should be tightened firmly but not so tightly as to reduce the downward pressure at the outer edge of the record.
e. Moving Well Tempered turntables from one location to another is best done by removing the motor and keeping the turntable set up and on a level surface. Place a soft cloth between platter and base to keep the platter from moving. If necessary the fluids can be drained and replaced. Use rubbing alcohol and soft paper towels for clean up.- 声底清澈干净、背景宁静、3D感强。。。《立体声》经常这样评价它,但是也正是因为它设计上的特别,我一直未能调整出想象中应该有的声音,目前还在奋斗中。
