[Amps] Holes vs. screen for chassis ventilation?

[Jim Barber]

Thanks for the referral. Just ordered a copy from Amazon.

For the group, does anyone have a well-maintained booklist for amps and 
general RF engineering? I recently dumped 30 years worth of Newark, 
Allied and other catalogs, and was rewarded with all kinds of space I 
didn't know I had... :-)

Thanks,
Jim N7CXI
