Jimmy396: If you turn the amp off,then back on, and everything is normal, the problem is a mismatch. If you turn the amp off, but when you turn it back on the transmit light on the meter is still on, you have akeying transistor bad. Bullshipper 537 Tex.

Problem can be fixed quickly by replacing "BOTH" 2N3907 (or equivelent) transistors. These are the "SMALL" black ones. There are only two of them and in your amp. You can get them at radio shack for about a buck. I will do it for you if you desire. Email me direct at tech307@copperelectronics.com
