JB7 Archive

JB7 production ceased in 2014 and JB7 technical support has been wound up but all the material from the support website was compiled into this document.

You can find the JB7 instruction booklet here.

A historic guide to how JB7 works can be found here.

Audiotech can repair JB7s and offer services to replace the display with a brand new VFD and also upgrade to SSD storage.
