[Premium-Rx] R-1449/WLR-6(V)

[An interested surfer]

R-1449/WLR-6(V) does anybody know how to open up this cabinet I removed one
screw from the front panel and the nut fell back inside... So I stopped
unscrewing things.  .So I'm looking for a diagram what's okay to remove and
what's not so I can clean the contacts on these controls... There's three
screws on the back that looks like that would help The thing looks like
it's welded in one piece but I know it's not... The back where the two
spikes are.. diagram or pictorial information would be helpful I know it's
a submarine radio but I want to clean it before a giant squid comes out
