Complete MCI JH-400B JH400 Technical Manual, bound copy

Here is a complete MCI JH-400B Technical Manual. This is a bound copy of the original MCI manual. It is approx. 70 pages in length and includes schematics, a large block diagram, and sections on Standard Features, Modes, Light Meter Option, Troubleshooting, General Instructions, Options, Specifications, Service & Warranty, Service Bulletins, etc. The schematics and block diagrams are printed on oversize 11 x 17 inch pages. For most of the modules, two versions of the schematic are included, to cover different revisions of the modules.

The JH-400B series is sometimes referred to as JH-416, JH-428, or JH-440, depending on frame size. This manual was specifically written for the early black JH-400 consoles (many of which had light meters for the VU's) and not the later cream colored version, though the schematics are mostly correct for the later version.
