[sdiy] Help with Hammond Solovox service info

[John Loffink]

As a side note, Alan Douglas also wrote Electronic Music Production in 
1973, covering the academic side of electronic music such as the RCA 
Electronic Music Synthesizer Mark II, computer based composing systems 
as well as commercial systems such as the VCS3 and the Synthi-100.  
Since the first edition of The Electronic Musical Instrument Manual 
dates from 1947, this has to qualify Alan Douglas as one of the earliest 
electronic music DIY hobbyists!
