SOURCE: Max. wattage for speakers w/ Technics Receiver SA-GX100?

I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.

Overload display


Follow the course of the capacitor using the printed circuit board track. It should leave to an semiconductor (IC or Transistor). Replace that. As that will be causing the cap to blow.

NO SOUND COMING OF THE SPEAKER


I have the same issue. The power comes on but no sound goes to the AU meters or Output. I have fixed dozens of cold solder joints on the circuit board but it did not fix it. I now am removing the RB1716AB board from the transformer and noticed the black retaining clips are broken. Intermittent connections? Maybe trying to get the clips now.

Overload sa-tx50


Most overloads are caused by the main output devices. They will go short circuit if for example speaker wires have come into touch. Another cause is high volume or a faulty speaker. Or poor ventilation around the amp causing excess heat.
The only cure is to replace the device(s) generally located on the heat sink.

Same problem


The overload indication tells us that there is a problem in the final stage of the amplifier section. This model uses an AMP-PAC or large amplifier IC (part number RSN-3305) which is now defective. If you can solder, try resoldering the pins on this IC. Sometimes a poor solder connection can cause a voltage offset that will be detected as a fault and shutdown the system like this. If the resoldering fails, the IC will need to be replaced. Parts cost will be in the $75-$95 range.

UNPLUG the receiver from the outlet. Take cover off. See the circuit board to the right of the dial (front facing U) behind the glass window. The bottom of those circuits are connected by pins that fit the other circuit board. Press them together or tie that corner safely to the back end using non-electrical wire (use poly-twine). When you do this you will not be able to put the cover back on. You will have to leave it exposed. If you like your receiver that much like I do - this is the solution I found. Put the receiver back where it is protected (from kids, juices, water, etc.) and enjoy your surroundsound again. You might have to do that to the other side. It worked for me. Use common sense when looking. Good luck.
