Title: IERC Tube Shields for the R-390A by Chuck Rippel, WA4HHG Post by: Steve - WB3HUZ on June 12, 2005, 06:42:45 PM The R390A uses 5 different kinds of heat dissipating, black, IERC tube shields. Installing the correct type and part number shield can dramatically decrease the operating temperature and in turn, increase the life of the vacuum tubes.
