Technics SU-G75 Amplifier Questions & Answers
Technics SU-G75 overload
I have the same problem..it will be required to remove the board and resolder "cold " solderings... None of above solutions have been helpful, but "you get what you paid for"..and I completely disagree...even if required, remove ALL audio power managing circuitry and replace this expensive original design with TI´s Integrated chips..using PWM technology..unless you want to go back to L6, ot Kts tubes..
No sound from stereo
Greetings
the power module is damaged and the components ... as you described, resistors burned and other components are over heated .
you need a service technician if you are still hanging on your baby :)
unless you are a technician .i will be glad to send you send you schematic.
i cannot post it as(PDF).
Technics SU-G75 has no sound
Hello
when the resistors are burned,means that the transistors are damaged, or the power module is damaged.
and in your case its the power module.
Hope this helps.
Only one input resultes in an output
John , Those units are KNOWN to have faulty switches. the most common switch it the TAPE MONITOR . try pressing it on and off several times to see if your other channel will come back on. If it does , even for only a second , you should try to spray a good quality contact cleaner such as De-Oxit cleaner. It should fix ya right up.
