[Heath] SB-401 driver tube shield missing

[Guy Giacopuzzi]

I don't have a tube shield for you, but I built my 401 in the summer of 
1974 (I think....) and I've been running it for about an hour a day, 
several days a week, since then...never have changed the tube. I do have 
a fan running in the rig though....pointed at the finals...
