Epiphone EA72 standby switch help needed

[MickeyB]

Have an Epiphone EA72 amp. 1965 according to the pots. Everything works good except the standby. Opened it up to find that its bypassed into the direct power. Is there a reason behind somebody doing this? Can I wire it back in and where? I read that it goes by the rectifier tube?.The standby lamp has no wires coming off it either. Not sure where they go. I do have the schem for it. I dont have a lot of knowledge of tube amps, sorry.
