I'm sorry to say that EB63 is not my favorite design. It uses a "brute
force" method of biasing that is very inefficient and generates a ton
of heat. Just have a huge heat sink if you plan on running the bias
per design...

I received the board today along with the Motorola engineering bulletin and
a list of construction hints and ran across my first problem. The bulletin
lists R4 as 33 ohms. The construction hints lists it as 82 ohms. The web
site resistor package lists it as 47 ohms. Hopefully they can clear this up
for me. I'll post the results when I get a reply.
