[R-390] Alternative to IERC tube shields?

Raymond.

An R-42, is the Hallicrafters R-42 "Reproducer".  It is a 12", (I think 
IRC.), speaker in a bass reflex housing that has ports on the lower fron 
for the bass.

They come with a 600 ohm too 8 ohm transformer inside and a capacitor to 
switch between "Hi-fi" vs "Communications".

While they aren't made or designed for neither the R-390A nor the 
SP-600, they do make for a nice audio sound.

Binding posts are standard on the rear.
