I'm rebuilding a neglected, 'monobanded' SB220. I love these old amps and have a nasty habit of adopting and restoring them. But right now, I am looking for a complete input network assembly.. Sometimes this assembly is called the "L-chassis". Band switch conditions aren't important, as I already have a set of those. The coils are the main parts I really need because I can 'fabri-cobble' the rest.
