Speaker

This is the top speaker assembly as removed from an Australian Made MM-2, but were also used in the MM-3,MM-4.  May have been used in the MM-1, but might have had a different shaped moulded plastic back cover than this one. Im quite sure this same model of speaker was used in all MM-1 to MM-4 machines.

I think from memory that the speaker was screwed to the metal plate from behind, and then the cover was placed over it and screwed in from the front of the plate.

The speaker used is an MSP (Manufacturers of Special Products) Australian made unit. (Note, they also made fluorescent ballasts used in some but not all Australian AMI machines)  The pink material was fibreglass wool, and would leave you itchy if you got it on you.
The plug has been removed, but was a 2 way version same series as the other modular plastic plugs used in these machines.

While this pic is not of a jukebox, this speaker is identical to the 12" unit used in Australian made JEL, and Diplomat machines - and possibly others. (Note: The transformer shown on the speaker in this pic was not used in the AMI machine.  From memory the label and stamp were same too.)

Australian MM-4 used a different unit to this that had a substantially larger magnet, and I never looked at what was in an MM-3, as I never had to repair a speaker in one.  MM2 used 2 x 10" units.

Plugs

Also on the previous subject of mains plugs used internally in Australian Made Machines, where I said USA type plugs were always used. The exception is with the G-80. Continental J, K, Diplomat etc. used USA plugs.

If you look carefully at the photo below of G-80 internals they used some unusual 2 pin socket with round pins, different to Euro plugs in that the pins were very small, IIRC Molex .093" pins that are used in lots of other equipment would fit in the G-80 power sockets very well and could be used to "home make" a suitable plug if needed.

Its unknown if there were followed standards for mains plugs across Australia in the 1950s when the machine was made, I remember reading years back that there were reports of various different types of mains plugs used in some regions, and cases of AC or DC being used in different areas.  For example Western Australia was still using 250vac mains until early 1990s. The rest of the country used 240v.

Please ignore that grey inline plug and socket next to the amp, these were added in the 1970s in order to fit a standard AUS mains plug, not only for bench repair of the amplifier, but and to provide an earthed plug and socket to comply with Australian wiring rules, They are not original. The green earth wire shown was added later too and was not original. Original was fig 8 lamp wire (white in colour) that was used.

Dia-Projektor – Slide Projector

Service Manual: "A slide projector, mounted at the top center of the phonograph, shows slides promoting record play. The slide projector holds eight 35MM slides and shows then continuously; one every 15 seconds."

This was removed years ago from an Australian made MM2, but have seen these also used in Australian MM3, though may possibly need different mounting brackets as the beam goes upwards rather than sideways. This unit is a 240v version for Australian market - even though it has the USA plug.

Amplifier

Amplifier RA-145:
This was made for Australian mains voltage, the selector at front left can be set to either 230, 240 or 250v AC. The National AMI Logo can be seen at right. The Phono input socket was not an RCA plug but a plug type I have not seen before - it is much the same size as the base of a bayonet fitting #44 pinball bulb and connects to the amplifier socket exactly the same way as the #44 bulb would go into a socket.
