[SixClub] 600 Watt Nice Home brew 6-meter amp using GI-7B

The cooling improvement will be made, I plan on changing out for some higher 
flow fans and then putting a plexiglass shield over the forward half of the 
rf compartment so that it forces all the airflow around the tube.  I haven't 
really had the time and I don't push her that hard yet, but it is on the 
to-do list!

The sockets are nice, they did a great job fabricating them.

Thanks and 73,

Scott
