A new Preamp Tube along with a bias adjustment is what the doctor called for

Much better way than to get a new amp to sound clean & hot. Drain you caps if you aren't also replacing them. Remove your old tubes and pop the new ones in. Perform a bias adjustment on your amp and you'll be happier than an antelope with night vision goggles!
