    i actually found the solution. some platters were pressed on lightly so you lift up on the platter and tap on the spindle . the platter should pop off.

Some t/tables have a rubber mat held in place with adhesive. Lift mat around spindle bearing, see if there is a "c" clip. Also if you can remove spindle look for anything that may be holding t/t. There is an outside chance dried lubricant has caused the bearing to stick. Brace the t/t base and with finger tips, lift t/t and with gentle rotating motion, try to lift off

I have the Philco suitcase Turntable CD player. Art No. 841.237. When I got it from my friend, she hadn't given me the ac adapter/power source. When I got it, I assumed she had given me the right one. I...


I don't know whether your philco is the same as my crosley, but I recently had an issue where the record player stopped turning and it bamboozled me to no end. After digging up the manual online, I found out that you had to lift up the tone arm and move it to the right (past the holding clip) until it clicked, and voila, the record player started spinning again.

I hope this helps!

Can't play records on my crosley cr66 turntable


You have to lift the tonearm up, and move it to the right slightly. This starts the turntable moving.

Belt on turntable needs replacing


should have a retainer clip of some sort right in the center of the platter. Should look something like this, you will need to take it off first.

Problem with autoreturn of tonearm


This very much depends on the type (and vintage) of the
turntable.

Very old turntables used a system of mechanical CAMs,
slaved to the main plater. Once engaged (usually through
a hinged/retracted gear-tooth), the platter would spin the cam,
which in turn would lift the tone arm, move it back home,
shut off the power and disengage itself after one complete
revolution.

This system could be mechanically triggered with the power off,
just by swinging the tone arm towards the center, and spinning
the platter manually by hand. To fix it you had to make internal
mechanical adjustments, or replace worn out levers, wheels,
bearings, springs, etc...

A more modern turntable will use electrical sensors,
such as a micro-switch under the tonearm gimbals,
which is triggered as the tonearm swings towards the center.
A second switch is coupled to the stop/ return button.

Once the mech. is triggered, it can derive its power from the
plater (as before) or use a separate servo motor to lift
and return the tone-arm. The viscously damped cueing
mechanism can also be involved in lifting the arm during
the return cycle.

At the hi-tech extreme, a microprocessor can control the
whole works through the use of selenoids and stepping
motors with optical or magnetic sensors to trigger it,
position it and disengage it.

0) Note:
During all testing, remove the record and cover the
stylus with its protective gate to prevent damage.

If the stylus slides out of the cartridge, like it did on the
Shure cartridges, remove the stylus gently and put it in
a safe place to avoid damaging it. You do NOT want to
ever drop the stylus on the spinning rubber platter surface.

But leave the main head and cartridge in place for normal
tone-arm balance.

Turn off your amplifier, or turn down the volume to zero, to
prevent damage to your ears and the speakers if the needle
does fall when it shouldn't

1) Assuming that this is a fairly modern turntable, with
a gimbal mounted tone arm (the large double hung ring
bearing at the back for swinging both ways) and a
counter weight for setting the stylus pressure...

and possibly an anti-skating adjustment as well...

It is fair to assume that the cuing lever is what lifts
the arm vertically, regardless of the swing return mechanics.

2) The premature stylus drop (during return) is therefore
caused either by a cuing defect, or by lift timing,
either mechanical or electronic.

The stylus weigh setting is NOT an issue here, that
is determined by the stylus and cartridge specifications,
and must be set correctly to prevent record and stylus
damage.

Note that both too much and to little weight is BAD.
Too much weigh is obvious, but too little will cause
mis-tracking, distortion and premature record wear.

Similarly, and incorrect tracking pitch or yaw will also
cause early damage, as will incorrect anti-skating for
a particular stylus pressure.

3) First of all, test the cuing lever at several different tone-
arm angles, to see if it stays up, or droops down with time.

If there is a problem, check the springs, viscous damping..

Take the ****** apart from below, and see what gives.
Is it mechanical, hydraulic, or electronic ?

4) If it is electronic, you have a control/ timing problem,
which requires a service manual and a qualified electronic
tech to fix it.

You should be able to check any sensors, switches
or motor yourself, though.

5) If the cuing lift system is mechanical, check the levers
and cams:
What is driving it ?
Is it broken ?
Is worn out ?
Is it out of adjustment ?
Is it slipping ?
Is it stuck ?
Is one of the springs all stretched or missing ?

6) If the lift is hydraulic or pneumatic, check for leaks.

7) If the manual lift seems to work, but the automatic return
drops it...

why?
what is controlling it ?
how is it linked it to the arm return mech ?
Is there a coordination/timing problem ?

Have fun.
Please rate my answers.

Most likely the grease in the whole system has started to stiffen or the motor is failing. This can be fixed. Try oiling the motor first. If that fails, I'd look at the motor driver IC as the most likely failing part.

Fisher turntable mt 6410 removal


Look at spindle bearing in center of t-table. There is probably a small ring lock there holding the table. Use a pick or small screw driver to carefully remove this ring.

Philco suitcase turntable / cd belt drive


Place the rubber band around the turntable and put a paper clip, bent up behind the rubber band. Start the turntable on it's spindle and you will be able to view that drive spindle on the right side, slowly pull the rubber band with the paperclip and drop over the drive spindle. remove paperclip and push turntable down seating it and replace the lock snap.
