Penetrating oil like PBlaster may help if the fasteners are ceased. If you rounded the nuts go to an auto parts store and look for a set of sockets designed to grip rounded fasteners...I had to buy one a few years ago for a stuck rounded exhaust manifold bold on my Lincoln and it did its job.

May also be it's designed to come out the back. I've got a different chassis Maggie from the late 40s and the front of the chassis has hooks to hold it down and those hooks only allow it to be removed from the back.

Ok, I'll see if I can get a look at the mounting bolts more carefully and see if it's mounted like yours was with hooks or if it was just screws holding it in from underneath.

I got the chassis out, it was held into place by the two bolts on top of the back and the chassis slid out the back.

the chassis has never had any work done to it except for having the record changer's audio output plug changed at one point in time, in fact this is probably one of the most original looking radio chassis I've seen in a long time.

See picture below

I tested a couple of the original paper caps inside the radio chassis and the caps still tested good yet, no leakage or anything.

The only thing that seems to be wrong with it is that I needed to replace the original power cord because it had some spots with broken insulation and exposed wire.

I got the record changer repaired and it works as it should, I have no idea about the cartridge as the original audio cable plug that connected to the phono input on the back of the chassis was cut off and modified so it don't plug into the correct audio input jack on the back (it was plugged into the FM tuner audio jack on the back rather than the Phono input jack.)

The plug I need to get the record changer's audio jack functional again is a two pin version of the plug pictured below, but so far I have not been able to find a plug like it nor have I been able to figure out what the plug is called (e. g. Molex, Cinch/Jones, Switchcraft etc.) and I would like to know if there's a specific name for this style of plug and if so, what it is, and if I can still get some NOS plugs like that yet?

Any help would be appreciated.

Yep, that's exactly what I'm looking for, I didn't realize they called those Jones plugs as well because I thought that's what they called the plugs that they used on the old Pioneer Receivers from the 1960s and 1970s.
