Welcome to the Phorum, Bob! You mention changing out a few tubes and replacing the power cord. If the chassis has not been updated this would be the perfect time to replace the caps and drifted resistors. Old parts will fail, and frequently like to take other parts along with them when they do. Take care and BE HEALTHY! Gary
