I decided to embark upon constructing/fabricating a set of 4355 lookalikes from spare parts and have enjoyed and appreciate the efforts of these outstanding forums. Please pardon my obvious lack of knowledge.
I've recently acquired a pair of 2440s with horn, only to discover one of the red terminal (binding?) posts loose and rolling around in the bottom of the shipping container.
There are some cob webs in the horn throat as well, however what appears to be a fine mesh screen at the bottom of the throats appears in good condition. Last user reported they had recently been tested and in good operational order.
I am tempted to dismantle the piece to determine how to repair the post, but am unaware if there is a gasket seal that might be damaged if I were to remove the horn and outer casing.
The loose terminal post appears to have a female threaded tap, however, the 2440 terminal space adjacent to the attached black terminal, is void a male post or bolt to screw the terminal back into place. I can view an off center nut or tapped female screw connector through the outer casing of the 2440 where the terminal appears to attach, but no obvious place to attach the post.
This leads me to consider either the piece has always been in disrepair, or that there might be a loose threaded bolt or nipple floating around the inside of the speaker casing, or stuck to a magnetic surface inside, so it might not be wise to energize the speaker until it is properly inspected.
I suspect this is a simple screwdriver and patience exercise, but I don't want to blunder into damaging the speaker inadvertantly by removing the housing if that is only performed when replacing the disphragm or any possible metallic gaskets.
Accordingly, I'm looking for an assembly diagram of the 2440, with replacement part nomenclature or part numbers, or am I making this too complicated?
Any corporate knowledge on this is appreciated. Thanks in advance for your patience in reading and considering this situation.
