A great Tech Tip from D-lab electronics. If you are planning to troubleshoot noise hiss buzz etc in your amplifier, make sure to utilize a dummy load resistor. If you use the internal amplifier speaker, the speaker can become a microphone, making everything appear sensitive, fooling you! The resistor technique snubs out that possibility. For your reference, you can use a low wattage type, since you are not applying much output. No need for a giant 100 watt resistor. I used 25 watt type, since I had a few spares around. Always be cautious when working around these high voltage devices. Have fun!
