Question about Philips Turntables

Turntable 45rpm speed has stopped working

33rpm is fine but when I depress the speed selector push-button for 45rpm the speed increases for a second and then decreases to below 33rpm and fluctuates under that speed. The deck sits on a platter which is driven by a belt around it and the motor spindle. The speed of the motor is controlled via the push-button selector which pushes a rod onto a lever which alters a switch position underneath a small PCB that connects via 4 wires to the motor.

    Brilliant! I'm no techie but I took the platter off, removed the pcb and found that the lever wasn't doing what it should. I tinkered, applied some pressure to the contact strips and, lo and behold, it now works! Thanks, ashburton, guru indeed!

Check that the lever is actually making the contact with the 45 rpm switch position and completing the circuit as it would seem everything else works. The only other thing it could be is a break on the pcb, but that is unlikely.

Hi,
Do on thing Oppen the Turntable and replace the 5 electrolytic capacitor ( 330mfd 16V,3.3Mfd 25V, two 2.2mfd 25V and 47mfd25v )in the circuit board. Also try to replace the 2 Vriable resistor ( 2K and 5K) in the circuit board of which one is for setting the speed of 33.33 and another for 45 rpm. If you need the srevice manual then just get in to the following link. You have to wait for some time until you will get a notification that Get the manual.

My turn table is going to fast when i play an record , what can i do to fix this? thanks


Hello the turn table has two speeds. 45rpm and 33rpm (rotations per minute) If you are playing a record that takes up the entire turntable you need to set it on 33rpm. For the records that only take up half of the turntable you want to set it on 45rpm. Setting the turntable on the wrong setting for a certain size record can make the record play to fast of to slow.

My Crosley turntable is spinning too fast at 33RPM


Mismatch speeds on older turntables is normally due to either 1) a kink in the speed switch mechanism or 2) a hardening and slipping of the rubber drive wheel.
A very small motor with a chamfered shaft drives the rubber drive wheel, and the wheel is moved by the speed control up and down the drive shaft to produce various rpm speeds.
In your case, it's likely turning at 45rpm because it isn't settling onto the 33rpm part of the shaft.
Piddle with the speed control, then count the speed (number of turns in a minute) You'll figure it out!

GOING FROM 45 TO 33


I don't know if this model is direct driven or by belt. If it's belt driven then the belt could be fitted incorrectly, or faulty. Another possibilty is that there's a fault in the motor control circuit.

It's very simple. Next to the "tone arm" (the thing you pull across towards your vinyl, and place down to produce sound) is a silver piece which you slide up and down to change the pitch (the speed) of the vinyl. This can be increased even further by changing the 35rpm setting (button near the start/stop button) to 45rpm.

Hope that helps

The 45rpm speed select button will not work


the 45 button is known as a push button switch. If the switch is affect, replacing should remedy, but it could be possible that the voltage variation on the motor is affected.

keep me posted.
