Do you guys leave your back panel on?

[jcs]

on my;

62 bandmaster
63 tremolux
71 smallbox 50
66 princeton
74 carlsbro 60tc

i do leave the back off because i swap tubes around and like to keep an eye on power tubes to make sure there is no redplating in a darkened room,plus i touch the power tubes from time to time to see how hot they are running.

if i am going to move the amp around much i reinstall the back to protect the tubes.
