Get your unit serviced by a reputable service centre or risk killing it with the strobe controller,your choice

They both work differently and Im sure they are different voltages too

the strobe will introduce a clicking noise to your beautiful sound,not very good at all

If you enjoy you music like I do then do it properly,
ask fo a quotes first or search for a replacement.

Hope this helps,please rate me thanks

Machine runs very slow and as I turn it up it speeds up some but is never fast enough to pitch


HI,
Try to change all the electrolytic capacitors on the circuit board. It will solve the problem.

My Gemini TT 02 gets stuck at 45 RPM. To get back to 33 you have to turn off and on again. Also the pitch is wildly out by about +7. Is there any way I can repair this?


Your terminology confuses.

Point 1. Why to you say, "Stuck?" Does it not make sense as a possiblity that the designers sought to prevent rotaton speed from being changed mid playback, especially on, say, an LP (long play) album with different side (stereo instead of 45 monaural) grooving. What would be the imperative of changing record speed in that manner...only one record type will play at a time. If changer, only one type record seriies can be played, all at the same speed.

Point 2. ...about "pitch...wildly out by about +7.

First, what are you meaning by pitch and by + (not -) 7. Since there is, to my knowlege, no record spin criterion known as pitch, are you referring to spin speed; hence to playback sound frequency, whether steady state or variable? If there is no user control of platter rotation speed on your unitn there would be little you can do other than to ensure all parts above and below platter are running smoothly with no drag or interference...possibly even lightening the record load on the platter, if a changer; and making sure records are clean to prevent slippage by washing with water or soap and water and air drying--avoid label. If your turntable is optically speed controlled (by timing marks on platter rim) those are typically adjustable to hasten or slow platter speed and therefore playback frequency pitch to your liking. "Wild variation" could reflect mechanical impedance as indicated above. Also check for record warping by trying known true record playback. Finallly, wild variation could be indicator of platter motor end of life cycle. Start pricing a motor if nothing helps.

I still don't follow the significance of the speculative(?) 7. Please explain if possible.

Adjust pitch not working on PS T1 Sony


Try looking underneath the turntable. There might be two speed presets one for 45 and one for 33. They could be covered up by stickers.

I have a Sherwood PD - 913 R and the pitch seems to be spinning out of sync which makes the RPM"s not right for 33 or 45 speeds, any help on what could be the cause is appreciated. There is a pitch...


The turntable motor might be the problem, if the grease is old it becomes hard causing the turntable to run slow, by your description we can rule that out since you indicate it runs to fast. therefore it is the voltage that powers the motor with a regulator "keeps voltage constant" or the motor itself will be the problem. The pitch control allows a small change in speed when required.

Thomas Pacconi Model TPC-MSE-800 turntable runs slugglish. 78 runs fine but 45 or 33 runs slow. I removed belt cleaned it and platter. I put a drop on oil still same problem. Do I need a new belt? This is...


Pjam,
Had the same problem & checked around on the net. Several people tried replacing the belt, but it had no effect. Spoke w/ several repair shops around the country and they concur with what I'd read on the net - bad motors. 3 or 4 repair/supply shops told me getting a motor would be impossible. Since I only listen to 33-1/3 LP's, I messed around w/ it a little and found a solution. Take the turntable out of the unit & you will find a small circuit board attached to the bottom. On that board is a small square blue fixture w/ a white circular "dial" in the middle (has grooves to accept a small straight blade or a phillips screw driver). This controls the voltage to the motor, which in turn controls the motor RPM's. If you set the selector switch to 78, you can experiment /w turning that white circular "dial" to slow the motor down. It isn't very hard to get the speed set properly. The down side is that you will only be able to play 33-1/3 LP's, but they are probably the most common anyways. I assume you could do the same to set the speed for a 45, rather than a 33-1/3. Down side is that you will only be able to play 1 size LP on the 78 speed setting, but it's an easy adjustment that can keep an otherwise in-op turntable functioning. Good luck!

My stanton t50 turntable plays too fast even when the pitch fader is at the slowest speed


You need to calibrate your pitch control. This requires a small precision screwdriver (similar to something you would repair eye glasses with). If you look under the turntable where the pitch control is you will find 2 small holes, 1 marked 33 and 1 marked 45. Turn the turntable on and set the pitch control lever to zero pitch. While the turntable is spinning insert the screw driver into the pitch calibration hole under the turntable and twist the potentiometer back and forth until the turntable pitch is zero (I believe clockwise is faster, counterclockwise is slower as you look up from the bottom of the turntable). This is a fine tune adjustment and will not require much turning to adjust the speed (1 or 2 mm's) either way should start to bring you into zero pitch. The platter speed can be verified by the little dots on the rim of the platter. They should appear stationary in strobe light on the power switch when you are at zero pitch. When you are adjusting the speed you will observe the dots on the platter rim spinning clockwise and then counterclockwise as you adjust the fine tuning. Fine tune the speed until the dots appear stationary and you will be back to zero pitch. You have to adjust the turntable at both speeds 33 and 45 using the correct fine tuning hole under the turntable. My personal experience is it is easiest to do this with 2 people. 1 person to hold the turntable level and running, while the other adjusts the fine tuning. Hope this helps.

The speed on my JVC L-A11 is too fast when set to 33. If I toggle in between 33 and 45 it slows down enough so the pitch and speed sound right. How do I fix this so I can keep it set to 33 rather than...


HELLO

There a few things which can cause this problem. First the speed change switch may be faulty or contaminated by dirt/dust. If I were looking at this deck I would spray some Servisol switch cleaner into the switch (you may have to remove the base of the deck to do it).

There should also be two variable pots which are used to set each speed - spray those as well - it may be a "dead spot" on the pot itself. These are the most obvious causes but if the problem still persists check the belt. If that is OK, then you may have a fault in the speed control circuit.

ALL THE BEST WITH IT (:-)

I just installed a Hunter five minute fan which says it is called the augusta. I have also installed several other hunter fans in my house through the years, and they seem to move extremely fast especially...


Speed is not a factor in moving air. You can move air with a little fan that runs real fast or you can move the same amount of air with a big fan that moves slow.

It is the pitch of the blades that moves air. Big blades with steep pitch moving slow are comparable to little blades with shallow pitch that move fast.

It seems to me someone is trying to baffel you with bull**** when they tell you CFM = watts or something similar.

The real question is, is the fan moving the air necessary to achieve the result you desire? If yes, speed is not really a factor.

Let me know if this helps you.
