Post a photo of the distorted output when driving a 100Hz test tone into it.

I couldn't really get it to lock in well... maybe wrong settings. We have noted that Q1 and Q32 they are (TIP107 & TIP102) are getting hot very quickly.

The TIP102/7 are being used as regulators so it's normal for them to get hot. Don't let them overheat. If they do and short, they could do extensive damage.

The signal is noisy but that doesn't necessarily mean it's going to sound distorted. Does it sound distorted?

Set the vertical amp to 10v/div and drive the output so that it fills the display vertically.

If you set the trigger to HF reject, it should lock better.

I can't seem to get a wave to form with my probe set to 10x and 10v without lowering the time delay so low you camera wouldn't capture the pic, lol.. So I switched it to 1x and put on 5v. This is the view

I don't see any real problems there.

How does it sound?

Sounds like a blown speaker... lmao but i know it to be good. Could the fact that he's using a phone be the issue? Ground problem? Even with no source it still sounds static..

Why aren't you using the signal source that you normally use?

Hi Perry,

I have since went and picked up the amp, Paul has been quite busy, and I couldn't expect him to drop everything for my amp when it was pro bono.

Paul advised there isn't any way for me to accurately test the .1 ohm resistors as you need more than a regular dmm to accurately do so. He also mentioned that this was a possibility that one of the 2W .1ohm resistors on the output transistors could be defective, so based on the low cost of the parts, ($.05 each) I opted to replace the twelve of them. This did not change the output using my ipod.

Paul advised when I was visiting him that it could be because the source was not connected to a source with a ground that was common to the amplifier. I took the amp out to the car and carefully tested with the RCA's coming off of the head unit in the car. Same problem as before.

Did you convert the sine wave to an MP3 file?
