Yup, just what I was suspecting. I think the driver or one of the output mosfets may be bad, but I'm no tech. This amp has a total of 5 minutes of talk time on it. Strange thing, when the amp first arrived, I tested it on my Yaesu with him listening at home. He said I sounded nice and clear. I was driving it with 10 watts. I brought it to his place and hooked it to his Ranger 2980, set it up for 10 watt drive, marked reference points on the mic gain knob for him, and all was working well. That same night we tested it with me at home, he sounded "decent", but for only a few minutes when it began to sound like his audio was failing to reproduce high frequencies. "s" would drop out, "th" would drop out, etc. Now he can barely be understood. He tied his last dime into this and cannot get it repaired, and that is where Tokin came to the rescue, which was extremely appreciated. But since this thing is not usable, I was going to play with it a little and see if I could figure it out. As I said, I'm not a tech, but I have soldering skills and can replace parts. I was just wondering if anyone is aware of this type of thing by the sound of it.

[QUOTE="Greg T, post: 776235, member: 42791"] Yup, just what I was suspecting. I think the driver or one of the output mosfets may be bad, but I'm no tech. This amp has a total of 5 minutes of talk time on it. Strange thing, when the amp first arrived, I tested it on my Yaesu with him listening at home. He said I sounded nice and clear.

"s" would drop out, "th" would drop out, etc. Now he can barely be understood.
