[Amps] FW: Power factor correction on tube amps

[George]

Once being an ISO9002 auditor, I found it difficult to accept that you 
can actually send defective product out the door as long as your polices 
and procedures are in place to manage the issue.
Consequently once I understood the reason you could ship non-conforming 
product, and be 100% within your ISO program it was a bit easier to push 
everyone to use it.
ISO9002 is not meant to be a quality program, simple put ISO9002 makes 
sure that you do what your polices and procedures say with no regard to 
quality.
