Replacing stylus on TEAC GF-330 tabletop stereo

The old stylus was already removed when I was called in. I don't see how to release the tone arm to tilt it to the vertical so I can see what I'm doing (as is, it tilts up maybe 20° from the horizontal). Further, I could really use step-by-step instructions to be sure that I'm doing this properly.

Firstly double check that the recordable discs you have bear the label "Digital Audio" on them as per the attached picture. Secondly what happens when you go through the finialise procedure in the manual? Do you see the ?FIn--d? display when you select the finialise button? Do you see ?NO TOC? and ?REC? indicators blinking at the next step? Please update the question & let us know if the information given was useful to you - Good Luck!

Electro Brand model number 9801: I played one record, now when I tried to play another the turntable will not rotate. Could the motor have burned out that easily?


Listen carefully with your ear to the turntable when you move the tone arm towards the record. If you can hear the motor running and the turntable is still stationary then the drive belt from motor to turntable has probably fallen off of broken. Lift the turntable, there's normally a metal clip holding the turntable in place, and locate the drive belt.

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.

Early tone arm pickup


On some record players there is an adjusting screw at the back of the tone arm that adjusts the tone arm drop in location but I don't think it will adjust the pick up point. That is controled by a steel rod under the record player deck that moves over and pushes a little trip lever near the center of the platter so that a gear is engauged and the end of record cycle is started. I'm not sure but you may be able to find an adjustment under the deck that is near the rotation point of the tone arm that will adjust that rod so that it will pickup later. Hope this helps some.
