HOT bake of VBOD (empty, background clean up) not so much.... I found that the RGA was cold due to a blown fuse in the output circuit of the Variac supplying its heat tapes. I replaced the fuse (variac setting for "HOT" bake-out is close to fuse rating) but now wonder how long this fuse has been open. It would be an easy thing to overlook as the power lamp on the variac remains illuminated - you wouldn't expect that anything was wrong if you were just looking at it. Hmmm...
Bake of VOPO assembly (Lisa B.) in VBOC is OK.
