Nomadd. I appreciate you taking the time to help me correct this issue. This is something I would not attempt myself. The preamp issue made it totally impossible to enjoy the sonar. Until I decide on whether I'm going to ask this local who is knowledgeable enough to do the bypass, what I did was I switched the 300a over to the Madison. I only use the Madison on SSB. I thought the preamp wouldn't affect the SSB receive as it did with the AM only Sonar.
I was right. Although 300a takes out my received audio signal on the Madison's in AM (as it did with the sonar) it doesn't do the same in SSB mode on the Madison. For now I'm just going to let it ride that way. On the other hand I don't like using equipment that isn't working 100%. But I am assuming and I hope I am correct that this issue will not cause any further damage to the amplifier or future issues with the Madison. I hope I am correct. I should get around to contacting the local whom I know can absolutely do this bypass after reading your replies and instructions. In the meantime the 300a is working very nicely along with the Madison on SSB. Output is 400 watts on my autek wm1 with about 10 watts, and no one notices the difference between the Phantom, or 350Z. Both of which I used in the past with the Madison for SSB use. Once again Nomad I appreciate all the time you've spent replying to my questions on more than just this post. You answered many questions along with many other members when I was having issues with the Phantom. I won't let anyone else touch the Phantom except out friend in Pennsylvania. So that's where the Phantom will be going soon. Once again I cannot thank you enough. Have a great week my friend. 73
