Book Synopsis
Updated May 24, 2023!! The V1083 Berkeley III Repair Supplement contains information helpful in repairing the Thomas Organ Vox V1083 "Berkeley III" guitar amplifier. It extends the more general how-it-works information contained in the Vox Owner's Safety Net with V1083-specific schematics, parts lists, board diagrams and other info on this one model. It is much more than a copy of the original factory schematics, and includes entirely redrawn schematics and board diagrams as well as working voltages taken from simulations of the circuits. This allowed sidestepping the occasional error in the original Thomas Organ service information.
This update corrects some subtle mistakes and inconsistencies in the original Thomas Organ service literature!
This information is suitable for the owner of a Berkeley III who wants to keep his amp running, or the service professional who may need a whole set.
