    Kris Mach 3+3 Amp -- muddied & weak audio

    Hi all! I just rebuilt (recapped) this amp, got fresh tubes from ebay. Fired it up, tuned correctly, but for some reason, reports back to me state I have a punch signal of 200W, but the audio is weak and "muddied". took the amp out and audio is fine at 3.5W base radio. Any idea? This Kris amp has a transistorized trigger over the usual 6BQ5,but it is a Kris manufacture mod, as the board stamped Kris. Any ideas? Name:  Kris (2).JPG

    The amp can only amplify whats input. Check the radio driving it. Some peaked and tweaked units are tuned for largest carrier, Back the carrier off and increase the modulation and try again.

    think I found the issue. borrowed my friend's Sencore Mini-Mite, and the 6JG6 measured weak near bad! I ordered a NOS tube from ePay, lets see if this will resolve the issue.
