[HAM] Recapping...

Hey Mike:

There was recently a Hammond factory promo movie from the 50's circulating 
around that documented the specific process that you are describing, showing 
the bins, the volt meter, and a tech adjusting the the magnets by hand.  I 
wonder if you were able to see that part of the clip?

For the guys who are into recapping, the specifications of that meter and 
the chart of voltages each magnet was being adjusted to match are sort of a 
holy grail.  I know you once posted that you have a lot of Alan Young's 
Hammond engineering records, but that they haven't been indexed.  Have you 
been able to discern what equipment the factory used,  and what specs the 
factory was rough-setting, before each organ went into the sound room for 
the final tune up?  I would venture that lots of folks on the list would be 
interested, especially if the specs or measuring equipment evolved over the 
years.

Regards,

Dave Bishop
