CHAMP ELECTRONICS
John Chambers has carried out a comprehensive repair, modification, and restoration service for all makes of valve amplification, including both musical instrument amplifiers and Hi-Fi audio equipment for over 30 years. During that time he has acquired a specialised experience of vintage British guitar amps, plus a special passion for the old Italian Geloso Audio Units.
John Chambers is the man behind Champ Electronics. He has been designing, building, and repairing amplification equipment since 1964. The purpose of this site is to demonstrate the experience and expertise that John has acquired since those early days as a schoolboy when he built his first guitar amplifier, right up to the present period of Champ Electronics when, as his main interest even in retirement, John is still carrying out repairs and restorations work to the great benefit of the vintage amplifier enthusiast.
NOTE: If you find that your make and/or model of amplifier is not shown on this website, that does not mean that it has not crossed the Champ Electronics workbench! Please E-mail John with any enquiries.
(All contact details for Champ Electronics and John's international counterpart in Australia, "Doctor Valve", are at the bottom of this Home Page.)
