More repair books for Thomas Organ
Vox amplifiers are coming on line at http://www.thomas-vox-repair.com/
The lineup now includes:
- The Vox Owner's Safety Net
- Vox Footswitches
- V117 Sovereign Repair Supplement
- V1181 Westminister Repair Supplement
The V1141 Beatle Repair Supplement and V1121/V1151
Buckingham/Viscount supplements are up next.
|
| 12/24/16

It took a lot longer than I
intended, but the Vox Owner's Safety Net is now available on line
at The Book Patch (thebookpatch.com), as is the Thomas Organ Vox
Footswitches Manual. See:
The Book Patch Bookstore: Vox Books
The Safety Net is an overview of the entire Thomas Organ Vox line
before the Series 90 amps, and covers the solid state amps from
the 1960s. The book is a technical repair manual on how they work,
and how to fix them in general. It's far more than a simple set of
schematics for the amps. I hope this will help Vox owners convince
more techs to do repairs and keep these amps running.
The Safety Net is an overview. For people needing more detailed
info on a specific amp model, there is a series of Repair
Supplements, one per model number on the way. These are being
written in the order of my best guess about what model was most
popular - and hence most needed today.
The Footswitches manual is a collection of all the footswitches
schematics and the technical insights on how to distinguish which
footswitch went with which amplifier, how to fix the lights, and
how to add/replace lights when needed. Also included are
mechanical drawings on some ways to make new footswitch assemblies
from scratch for an amp that's just missing them.

A tube
amp rectifier current clamp. This inserts between your rectifiers and first

power on and coming out of standby to soften the surge of current. Although
this is not exactly the same as a tube rectifier does, it's quite similar in
results.

Dinking with some Neovibe derivative layouts. Here's a comparison
