Hello All,
I have the service data for this set, but I don't have the actual radio here. Does this radio take the standard 3 prong speaker plug? The schematic seems to indicate that it does, but maybe someone knows or has a picture of it.

Thanks,

Dave

The 56 Mercury 6BM/6BMS does not use the Ford 3-pin speaker plug. If you look carefully at the diagram on the schematic (AR-6), you will notice that there are 4-pin openings on the socket. The socket is set up for use with just a front (single) speaker, or with front and rear (two) speakers. A single front speaker has a 2-pin plug that fits horizontally in the top 2 socket holes (so marked on the radio chassis). If a rear speaker is also used, the 2-pin plug for it fits vertically (also marked on radio chassis)and has one longer pin. The longer pin goes in the center hole of the socket. There is a set of contacts in the center hole that are opened with the longer pin and allow use of the built-in speaker fader in the radio. Easier seen than described!

MAG,
I have the service data and have studied it. To me it looks like nothing connects to the middle pin except the fader control, which is inside the radio. Where would I find the correct speaker plug? I'm going to need one.

Thanks,

Dave

It should be clear how the socket works when you have the radio in hand. Where to get the speaker plugs? Good question! From a junked 56 Mercury? You may have to fabricate the plugs with pins from old junk connectors. I made a speaker cable and 3 pin plug for a 37 Olds radio just last week. I used the pins and phenolic from a junk vibrator base. A Dremel tool with cut-off wheels comes in real handy for such work.

MAG,
I have a Dremel somewhere and I have junk vibrators. So I should also be able to make one.

Thanks,

Dave
