Augh!!! Here we go again! As if the
engineer's design is what actually gets produced! In something like this the
engineer has to make an impassioned plea to upper management, if not executives, to get his amp & speaker design approved. Everything else is packaging and potshotted by accountants and ad men!!

(Nothing personal, WI.

Halfway kidding.

)
Amen, Phil!! You must be a fellow
engineer! I suffered such slings and arrows early in my career.

But it didn't me long to learn to fight fire with fire and come back with, "It was your manager that vetoed the ['costly easy-to-use valves' or whatever the complainer
wanted], and said that his people were experts with the ['standard, cheaper valves' or whatever the complainer
got]!" All the managers wanted the brand new Cadillac projects, but at the used Yugo price! We did our best to build 'em a serviceable Ford, Chevy or Dodge. Then they either used 'em to good effect or
refitted them to a new Cadillac or a used Yugo!
Sorry! Retired 9 years and still couldn't keep my [virtual] mouth shut on some trigger issues.
