LP12 set up query
Posted by: Brucie on 10 November 2003
I've had my LP12 (with Ittock arm) serviced recently and have noticed that:
(1) The bounce on the arm board does not seem to last very long. Previously after a service you can just touch the arm board and the thing bounces a fraction for quite a while. I always thought this indicated a good suspension(?).
(2) the arm board (cartridge end) is not flush against the metal top plate, it is a little higher. Conversely the arm board (counterweight end) is not flush, it is a little lower. The LP12 is resting on a flat surface and when it plays the arm does appear to be parallel (as far as my eye can tell).
Am I being paranoid and have simply not noticed these things previously? The deck sounds good but I'm listening to it too critically at the mo.
Any thoughts?

Bruce,
Check the level with a good circular level. I purchased one from a local hardware store for less than $3 US. First check the surface it is resting on, then the platter near the center with the felt removed. Everything should be absolutely level. Nearly all problems start with the TT not being level.
Most likely reason for a sloping armboard is that the turntable has been adjusted for level on a surface which isn't level.

sounz well dodgie 2 me.
Take it back for a reset woz in a Linn dealer [would not have thought so]
Setting up Linns iz not rocket scyence, very straightforward if you have the right kit, which of couse a Linn Dealer has

j8hn wouldn't it be just as quick on a keyboard not to use all that annoying shortcut rubbish?
Regarding the linn, it sound like in the setting back up in your gaff one of the springs needs to be rotated. turn off linn and get under it whilst its level, try turning the spring on the end that dips make usre to turn the whole spring and the grommets.
Otherwise you may need to tightne or lossen a bolt. on the end that dips it may need to be tightned slightly. or on the end that sticks up loosened. Its a bit hard to explain but youa re aiming fore the arm board to be dead level with plate.
I have moved my LP12 from one end of the room to the other and its managed to get all scewed so I wouldn't be immediatly keen to kill the dealer.

When you use one of those little circular "bullseye" type levels, you should have an LP resting on the platter. Place the level at the approximate area where the stylus will contact the records surface.

The LP12 should not require re adjustment after moving it as long as you remove the outer platter first. This works even if you turn the TT upside down, which is the best way to check the suspension is correctly centered. Removing the platter unloads the suspension. Unloading and reloading the suspension is always the final step of the setup and doing so once the correct adjustments have been made should not have any affect.

Thanks for all the comments. I'm glad to hear that others also think its odd. I've decided to contact the dealer rather than fiddle. He is not a LINN dealer as such but has been trained to service the LINN.
This is not the first time he has serviced it and I always thought he did a good job. Unfortuantely there are no substitutes here in Durban, South Africa(except me doing it myself but without the proper jig that must be v.tricky).
I just hope when my new ARO arrives in April he will do a good job on that.
Cheers

I would respectfully suggest that your LP12 setup could be improved. I'm quite sure a well set-up LP12 should easily manage a good portion of the M25 in the back seat of yer motor without screwing things up badly.

As far as my experiences in England go, the deck did survive the 20 min trip home (from Basically Sound, my previous dealer, near Norwich). I felt that they always did a great job.
I think this guy here did it OK the last 3 times I've had it done, so maybe things did go astray for some reason this time.
He is visiting my home on saturday (after the Rugby World cup game!).
cheers
