So, I picked up a very nice SA-8100, and I absolutely love it. Sound is great, and I really like the three range volume control. However, I have noticed two issues at this point.
1. The amp will play fine, but somewhere between one and five minutes of play time and the protection circuit will engage for 2-3 seconds cutting the speaker output. After that everything is fine and plays without problems. I'd say this happens about 80% of the time after turning the amp on. Once it a while it does not happen. Does not seem to matter what input I am using. However, it won't happen if no inputs are on.
2. There is also a hum heard in the speakers when I have a phonograph connected to Phono 1. Tried two different turntables, but with same result. However, I do not have this issue on Phono 2. So, at this point I just use Phono 2, but would like to solve this issue on Phono 1. The hum only occurs when a turntable is connected to Phono 1. When nothing is connected to it, no hum.
Any ideas on solving these issues would be appreciated.
