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, together with John's international counterpart in Australia, "Doctor Valve", and John Wood Electronics & Transformers (UK), together with Robert Kingsbury Joinery/Materials/Coverings/Fascias (also UK) are at the bottom of this Home Page.)

NOW...............TO ADD FURTHER VARIETY AND SERVICES TO THIS

Please let me introduce you to my long-standing friend Bob
Kingsbury. What this man can’t do with wood & covering materials isn’t worth
mentioning. So now, if you want a speaker or amplifier cabinet making, in plain wood or Tolex-covered to your
choice/design, a copy of an original cabinet, or a refurbish/renovation of your existing equipment then…..this is the man who
can!
Bob also has the equipment/facilities to make and (or) copy virtually any amplifier front/back facia panel
too.
Bob’s contact details are provided below:

Please note though that Bob's work/services are undertaken independently from Champ Electronics in all respects.
