Runs fast about 78rpm.

stylus should be same for all. It's the speed settings that make the difference. If you player does not have dial with 33/45/78, then you wont be able to play them.

New stylus needed, make sure you have a proper lint grabber and that you are instructed properly, when i was using 78rpm a crackely sound was associated with a very much used stylus, Replace

Make? Model?

without this information no one can help you.

best bet is vinylengine

BSR tended to make old style turntables, ones with a 78rpm speed on. I don't the model in question, but if it is a one of these, there's not much to them. Basically a rubber tyre runs inside the rim of the platter, while the tyre is pushed on a mains powered motor, in at least 3 different positions (depending on the speed). The tyre moves up and down depending which speed is selected.
Speed faults are caused by either a bad motor, or muck, oil, or grease in it.
A faulty tyre that is worn and doesn't push on the motor or platter anymore or not hard enough. Plus of course tyre height setting wrong.

Follow the wires from the motor to the control board. That is where the problem lies.

It depends what kind of drive this model has. It's possible that since this is a model that has the 78rpm speed it could use the old type of drive. If so then what happens is that a mains powered motor has a three position pole on it. A rubber tyre presses on each section on the pole. The speed switch manually moves it up or down. The tyre presses on the motor and on the rim of the platter. A worn tyre or one that is not moving to the right section on the motor will cause incorrect speed.
The only other form of drive would be a belt, but not many belt drive turntables were built with the 78 speed of this date.

The cartridge must have a stylus for 78rpm records. If the turntable does not have a 78 speed play it back at 45rpm. Record it and using the software you have or get one such as Audio Cleaning Lab, just select the option to convert from 45 to 78. You can then carry out any audio modifications to clean it up, then save it as an MP3.
Never use a 45/33 stylus to play a 78 and never use a 78 to play a 45/33 record.

Yes! The grooves are different on 78rpm records. By the way they are called "stylus" when you go on the hunt for one.

slow speed is brown, fast speed is purple.
hope that helps.

probably the selecta switch is faulty this normally changes the wiring to motor
