D-lab series Basic Training Tube Guitar amp repair Fender Champ Low power is the transformer bad?

Another cool problem dished out by Fred & Fink. This time a Fender Vibro Champ having a low power output issue. I performed my routine cap change assuming that was all the amp needed. To my surprise, the low power symptom remained. After some research & inspection, the culprit surfaced. A unique problem, almost fooled me. Always exhaust your resources before condemning components, especially when it could be a pricy transformer! Basic training fun from D-Lab electronics. Remember these original type filter capacitors can be purchased from Amplifiedparts.com. Maintain the original performance & look of your classic amp!
