 P.R.O.F.I.T. plus those poorly engineered FM radios that couldnt 
"officially" be modified.
OTOH with B style tubes installed service life increased many fold which

franchised shops and were tired of being screwed every time a unit had to be 
serviced. Taking business away from Motorola in particular was a pleasant 
task.
