Mike -
These tubes should NOT have shields on them. The shield base is enough shielding and adding the
shield only increases the heat, decreases the tube life. Leave them OFF.

I am cleaning up a TR4 for a friend and have noticed that the shields are missing on v6 and v7,
although the shield bases are in place. Interestingly, the shields are missing in the chassis
photo in the manual on the BAMA site. Anyone know how critical these two shields are? I would
think that Drake would not have put them in there if they weren't necessary. Also, does anyone
have a pair of these that they are willing to part with? The V6 shield is for a 7 pin and the V7
is a 9 pin (wider and taller). Mike
