The 3K Classic X used the 8877.
The 3K Classic X MKII designates the change from 8877 to the 3CX1200A7 only.
I created the HENRY reflector on qth.net to help ANYONE who has a HENRY or
wants info on one.
Every manufacturer has or had problems and HENRY is no exception.
What is done about those problems, that's important.
It's since early 1998 when I signed on in the rep and distributor role that
I can speak and be responsible for.
