I recently purchased a circa 1970 sf champ. I heard how great these things sound when you crank them, but even when i dime everything it doesn't break up at all... Is there anything I can do to fix this? New tubes? Or am i out $350?
Maybe wrong or worn out tubes. Start there cause it sounds like maybe a preamp tube is wrong or way to cold. Yes a good SF Champ sounds pretty sweet cranked.

You scored the amp at a fairly low price, so congrats there. Use the money you saved to replace the tubes. If that doesn’t work have an amp tech make it do what you want.
Retubing a Champ is cheap and easy. Very few tubes and they're all plug and play. Do it.
