"The Hammond Organ: Beauty in the B" by MarkVail (1997) is the only available reference book on HammondOrgans that I know of. Really, it's really not much of a reference book --- more of a "coffee table" book.

For information on where to buy the book, see BeautyInTheB.

The first edition of the book contained numerous errors, some of which are listed here. (The second edition is rumored to have corrected at least some of these errors.)

This is what I found on the first pass. I'll list more later. Feel free to correct the corrections -- JeffSimpson

Thanks for adding this list Jeff. I've just fixed the markup a bit. -- JeffDairiki


The A-100 is not a locking top console.


Page 14: Caption is describing the Hammond organ replacing pipe organs. Picture shows a pipe installation.

Page 42: Omission of drawbar knob differences in color and stamped harmonic designation.

Page 43: Keys C# through A call up drawbar settings (presets), not C through A. C is the cancel key.

Page 46: The tab shown is not the overall percussion volume control. It is the overall volume control.

Page 71: The A-100 series does not have a stereo reverb system. The B-3/C-3 and the A-105 are not identical component-wise. There are wiring, component, and hardware differences.

Page 73: There is only a 25 pound difference between the models described. This includes pedal clavier and bench, which are not carried in one piece with the instrument.

Page 99: The pictures of a Grand-100 being assembled have nothing to do with buying and maintaining a B-3.

Page 118: A French Provincial A-100 is an A-102.

Page 132: Most players left the covers off in a futile attempt to be heard next to a guitar/Marshall stack(s).

Page 133: B-3, XB-3 what's the difference, right?

Page 131: Can you tell the difference between a 145 and a 142 from this angle?

Page 141: Ditto.

Page 142: Top - This is not a 147. Bottom - This is not a 122RV.

Page 198: I dunno, looks like an illustration to me, not a B-3 right out of it's shipping crate.


Page 141: The 122 and 147 have identical connectors. B+ is plate supply, not grid supply. The 147 being unbalanced does not induce noise, it make the system susceptible to noise from other sources.

Page 142: Major components are the same between a 122 and a 147 output stage. There are differences between older 122 and 147 amps. I can't tell you about the later HS products.

Page 145: The 60 and 70 were also sold for use with the Wurlitzer 200 piano.

Page 150: 122 amplifiers use 2 12AU7's but only one of them is used in the preamp. Half of the other one switches the relay. The other half of this tube is not used.

Page 216: AWSOP wasn't recorded with a B-3.

Page 216: Rhoda Scott is sitting at a Hammond B-3000, not XB-3.
