Hi All, my first post on this forum, im so glad to have discovered vinlyengine, it's truly the wikipedia of turntables.
a brief background; im from Bombay, India. im rediscovering Vinyl, my initial exposure was my dad's LP stash, which was not much, but a decent one to boot with. running on a basic HMV turntable.
Fast forward to now, i was on a lookout for a decent TT which would offer the bang for buck. although i was looking for a garrard 401, as luck would have it, came across a LP12 Sondek locally (very rare to see Linns on sale in india, of those who have it, never part with it); as luck would have it, owner had a G401 and this LP12 and was looking to part with the LP12 for some reserve cash.
So, what i got is, a Table circa 8th Oct 1979 with a Linn Ittok LV-II (in pristine condition) and a basic Shure cartridge. none of the parts are replaced, table is in Original spec (aluminium shade suspension springs, plain chassis, white inner bearing lining et al.)
Vinyl engine is flooded with so much informations on this table that theres hardly any new question to raise...im new to this forum, so please pardon me if this topics have been covered a over a thousand times...
As obvious, im smitten by the upgrade bug, but dont want to go at it full throttle...jsut want to get a better feel of the table first and understand "whats the purpose behind" a step rather than "do it coz everyones doing it" approach.
Based on my understanding in this forum, these are some of the basic steps i need to take first
1. replace belt
2. replace oil (have placed an order for Mobil velocit No.6, 5 ml)
3. replace suspension springs
i plan to tackle these three things first...
I notice current belt is a damaged one and does sit tight in the lower groove of the pulley, 1/4th of it rests on the upper groove of the pulley and the rest lower groove, is this correct positioning?
some questions related to replacing Oil...as i understand, the steps include:-1. remove platter
2. remove spindle
3. pour in couple of drop of oil thru the bearing well
4. let the oil stay for couple of hours
5. turn the table upsidedown on a flat surface with the tone arm section firmly locked in and prefereably hangin free on a side of a table
6. let it stay for half hour
7. repeat above process if required
8. empty 2.5 ml of oil in the bearing well
9. apply little oil on spindle with cotton swab
10.put the spindle back in place, let it slide on at it's own pace
Suspension Springs: ahh well, i know..the linn bounce and what not...if there is one topic re-hashed to death on the LP12, i guess it has to be this. Please pardon me for going at it again...my question is lil bit more naive..
1. should i keep the tone arm in place as it is?
2. Would a older tone arm board be still ideal for setting up (my reference is only from sonic standpoint and not cosmetic, i like it the way it is)
3. any step by step process to de-assemble the unit; the way i understand it
a. place TT on a flat surface with enough space underneath to work with
b. unscrew bolts holding suspension springs
c. replace with newer springs
d. adjust tension
e. any important step that is missed above?
4. is there a specific pattern that is to be followed while tightening springs? (i understand we must check each spring for tension and preferably use to tighter one under the tonearm side and the softest one near motor
5. does the arm board need to be tuned so that it floats exactly in level with the plinth?
6. when i remove the platter and spindle revealing the bearing well, i see the 3 screws holding it slightly off center, is this ok?
Please correct me if i've got it all wrong. and, i truly apologize for such a long and winding thread...
ill post pictures by tomorrow or day after..to highlight some current issues as outlined in my query above...
