Question about Audio & Video Receivers
My Sons Peavey Blazer 158 amp has developed a fault. On the Clean channel you get significant distortion. All other aspects of the amp are fine. Is there a solution? Can I buy a replacement head for the amp? as it seems to me that the fault lies in the electronics of the head
Well, the nice thing about the newer amps is that the actual amp circuitry is all contained in a module and you don't have to do much troubleshooting. Just replace the module for that pair of channels. Bad news of course is the modules can be pricey. Should say right on it the part number, order it from mcminone.com or whoever, solder it in, use new conductive grease (many times I think these modules fail because the grease gets old, the module overheats and toasts) and you should be fixya'd

There is a defect in the pre-amp section of the unit. Without seeing it and taking a few measurements, I can't give you any particulars. A rough estimate for a repair wouldbe about $10-$25 in parts plus the local labor rate.

Usually this is caused by a cellphone in the area. The cellphones send a signal to the cell tower ever few seconds, when they do that, it makes it sound like the wireless mike is losing its battery, when in fact, it is the cellphone interfering with the signal. A simple test would be to power up the system when you can verify there are no cellphones turned on and try the wireless system. Then turn the cellphone on and repeat the scenario.

Phono inputs are designed for turntables only. Any other device will provide too high a signal for that input to handle. The phono input has an extra amplification stage built in. The distortion is because of the high suignal level being supplied to the input. The only way to get this to work properly is to purchase an antenuator which will decrease the signal level to the phono level.

I have similar problem with my Onkyo Tx-SR600. It only happens when it's in surround mode. When switch to Stereo or Direct, the scratchiness go away. Still trying to find a solution to this problem.
