Some say that they are and some say that they are not !
My A-88T was not !
Incidently , I had a heck of a time trying to get the biasing procedure and specs from the N.A. distributor , they were not included in the user manual . Several emails went unanswered . I finally had to get them through a member here .
Good luck .
