1975 Fender Silver plate Vibro-Champ amplifier. Original Oxford 8CJE-1 Fender Special Design speaker. I don't see a solder connection that was touched inside. Codes & part #s in the pics. Very well cared for going on five decades old. Classic Fender tone. Surprisingly spacious Fender cleans with the ceramic Oxford. The Vibrato works perfectly and sounds tubely musical. Excellent with pedals. A true Made In USA sonic time capsule Great as a bedroom beauty or, at 20 lbs., a very gigable grab & go amp when mic'd. It's a Champ! Thanks for looking in...
