Rockola look alike amplfiers

[shrimpeater]

I have a 47760-a in my 446, and a replacement coming in. 
Question I've been pondering is ,does the 45730-1a and 47160 work in these machines as well. 
I see the 445 is identical,as in the mechanics of the machines(record changer and mechs,all 400 series).Only differance in the 445 and 446 is apparently the cabinet,so I wonder why the amplifiers would be differant. 
These is also a 52280 amp that also looks the same from the outer shell.

It's hard to be precise but generally if the amp looks like it fits, then it usually works fine. And if there is an issue, then it's not normally difficult to rectify.
