A Pictorial visit to Boulder Amplifier's Factory

Posted by: Steven Stone at 2:02 pm, March 21st, 2009

 Boulder Amplifiers is located in a small semi-industrial area south east of downtown Boulder, Colorado.
With 20 full-time employees, all Boulder products are designed, and manufactured almost entirely within its factory.
Only Anodizing is done elsewhere.

One of the only processes Boulder doesn’t do in-house is anodizing.
To avoid flaws, parts being sent out for anodizing are bolted to aluminium sheets, which are then placed into wooden shipping boxes.
The anodizer never has to touch the actual parts because they are bolted to the sheet and the entire unit goes through the anodizing process.

Boulder amplifier products are essentially custom-made. Parts modules are assembled, but are not put into chassis until an order is received. This particular set of circuit boards are reserved for PN 2065.
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 
 
 
 
 
 
 
 
 
Boulder has several CNC machines for making all their own aluminum chassis parts.
Here Ian, who’s been with Boulder for several years, sets one up for a run of bottom chassis parts.
