The Maroon Elmencos can stay - they are film, just like an Orange Drop. RCA and Zenith loved them - I've never seen one go bad.
As to shielding, any ferrous metal will work - I've used perforated (1/16" holes) metal before - came straight off of an old Phase Angle Voltmeter. Also, make sure you have the 6BK4C regulator, or a 6EL4A. They are the regulator tubes with the longer anode that provides the optimum X-ray protection. Of note, patented by a female RCA engineer!!
