Thanks!  That is good to know, as the power supply in my VLC has issues.  As it stands, the VLC was replaced with a VAXstation 4000/60 a friend gave me.  I’m still using DEC drives in a BA350 (originally a DEC BA353).  At some point, I should simply move it to a VM, as I’ve done with the rest of my DEC systems.  I’d like to convert either the VAXstation 4000/vlc or the 4000/60 back to being a desktop.  Right now the 4000/60 is mounted in a rack, and is my DECnet Area Router.
