Hi Les, as a first step, I would disconnect the speaker cables in the Technics su-x501 and test if the same thing happens, if so, there could be a problem with the power supply or also with the speaker output
If it does not turn off, then I would start checking the speaker cables, along the way, in case there is any peeling, which could cause overheating
Once the cables were checked, I would connect the speakers one by one and test with each new reconnection until the source of the fault was detected
I hope you can solve the problem

Hola Les, como primera medida, desconectaria los cables de los bafles en el Technics su-x501 y probaria si pasa lo mismo, si es asi, podria haber problema en la fuente de alimentacion o tambien en la salida de parlantes
Si no se apaga, entonces comenzaria a revisar los cable de los bafles, en su recorrido, por si hay alguna peladura, que podria generar un recalentamiento
Una vez revisado los cables, iria conectando de a uno los parlantes e iria probando con cada nueva reconexion hasta detectar el origen de la falla
Espero que puedas resolver el problema

Hi Thomas, as you say, it's not the engine, nor the integrated engine
Most likely, the pitchel potentiometer that generates the problem
I would try to clean it, applying a small amount of contact cleaner and test if there are improvements
Keep in mind that it is the Pitch potentiometer that is changing the speed
Comment if the suggestion served
Regards Franco Dosil

Hola Thomas, por lo que comentas, no es el motor, ni el integrado del motor
Lo mas seguro es que el potenciometro de pitch el que genera el problema
Yo intentar?a limpiarlo, aplic?ndole una peque?a cantidad de limpiador de contactos y probar?a si hay mejoras
Ten en cuenta que es el potenciometro de Pitch el que va modificando la velocidad
Comenta si sirvi? la sugerencia

It sound like the main power amp has failed. Look at whatever is on the big heatsink as to the cause. As with any device from "friends" it could be that someone has tried to fix a fault and made a mess. So look carefully at the soldering to any of it's parts.

Hi Jan, there is a fuse that you should check, if it was burned, replace it only by one of equal size, never of greater value, it could be drastic
The switch of your Technics, is electronic, works with a relay that connects the power to the main transformer
This electronic ignition is powered from an auxiliary transformer (Stanby)
If you hear a noise when you press the Power key, it means that the relay is working and you should check the fuse that tells you
If you do not hear anything, the auxiliary transformer could be wrong
I sent you the link of the service manual of the Technics SA-GX690, which is the same in this part of the circuit
I hope you can solve the problem

Hola Jan, hay un fusible que deberias revisar, si estuviera quemado, reemplazalo solamente por uno de igual medida, nunca de mayor valor, podr?a ser dr?stico
El interruptor de tu Technics, es electr?nico, trabaja con un rele que conecta la alimentaci?n al transformador principal
Este encendido electr?nico esta alimentado desde un transformador auxiliar (Stanby)
Si escuchas un ruido cuando presionas la tecla de Power, quiere decir que el rele esta trabajando y deberias revisar el fusible que te comente
Sino escuchas nada, podr?a estar mal el transformador auxiliar
Te env?o el link del manual de servicio del Technics SA-GX690, que es igual en esta parte del circuito
Espero puedas resolver el problema
