Up for auction are two very rare and useful Hammond organ manuals No.10 and No. 11.

The No.10 manual covers the principle operation of vibrato/chorus, selective vibrato, and touch response percussion control of many of the older Hammond organ models. It contains diagrams featuring "console vibrato chorus" as well as spinet model "M" series. Some of the other diagrams include the models AV, BV, BCV, CV, DV and RT.

The No.11 manual offers amplifier and preamplifier system schematics for the B series, C series, and RT series organs. It also contains schematics for many of the Hammond tone cabinets.

It is available as a downloadable file derived from a source document in the public domain. There are 46 pages to this manual. The files are readable and printable using Adobe Acrobat Reader obtainable for free by Adobe. This manual is also available in mailable media, for an additional $1.50.

Thanks for looking and good luck bidding…
