A friend of mine gave me his late brothers GFA 555 amp for which I have
a question regarding the input jacks. It seems that his brother had
this set up in a bridge configuration, and looks like he may have
removed the outer shields of the RCA Phono input jacks. I would like to
reverse this and use it in the twol channel mode, but after seeing
these jacks I don't think it is as simple as moving the switch back to
"non-bridge". Was this normal practice to remove the outer shields?
were they designed to be removed?

I sold my 555 a while back but, iirc, there was no standard provision
for removing the shields from the jacks and, frankly, no good reason.
You need them to physically support the connection at the jack and you
can ignore them by not connecting them electrically. I guess you'll
have to replace the jacks.
