Distorted right channel

If it sounds like static, and the bass really effects the sound it is most likely going to blow.
I would suggest taking it easy on the volume or switching your volume settings so its more on the left speaker than that right, but still with sound coming out the right one. Just so you don't blow it as fast.

You just need to replace your volume knob for a better one , a couple of bucks 10 dollar

Hello there, I have the same amplifier and now it has the same problem on the right output. Have you found out how to fix it? Thanks!

Sounds like Tube Microphonics to me...
Change the 12AX7 (I guess) for that channel for starters.
If not, some condenser went crazy.

I SUSPECT THE CHANNEL IS BLOWN.YOU COULD TRY OPENING THE UNIT AND SEE IF THERE IS ANY GLASS FUSES.ONE MIGHT BE BLOWN.IF NO FUSES THEN TAKE IT TO A TECHNITION FOR REPAIR.THAT WILL BE YOUR ONLY OTHER OPTION.I KNOW,I HAVE HAD THIS HAPPEN TO ME.GOOD LUCK

if front left is working it is possible u have a dry solder on ur right channel line. try resoldering or if u want to know exactly where dry solder is, shake gently every right channel components and connections. if resoldering does not work it is possible u have a faulty ouput amp for ur right channel. if ur not sure about this i suggest u get it checked by a qualified tech.

The new boards multiplex the connectors on the back panel to maximize use. Open the Realtek control panel and configure for sterio 2.1. Also, these new boards do not provide any power drive, so to get decent volume, you will need amplified speakers.

The distortion might be caused by a resistor. The loss of volume could be the capacitors, but you could try injecting signals into the transistors to see if any has gone. They can cause the distortion and loss of signal. If you apply a soldering iron to any part it will heat up quicker, or you could also use a hairdryer for the whole thing. You can also get a freeze spray that cools things that have heat sensitive faults (available from electronic parts shops).

Sounds like you have lost the power amp transistor(s) or IC for this channel.

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
