An 8 ohm speaker would be just a trifle lower in volume than a 4 ohm, at the same volume control setting, which would be remedied in all practicality by just turning up the volume a little more. A new output xfrmr. would not be needed. Of course you're looking at the insides and I'm not, but maybe a larger speaker could be mounted differently from the way the original one is. Just a thought.

I'm going by the Sam's Photofact. I did a double take when I saw it. They list the impedance as 2.6 ohms. I thought it was a typo but then for the output transformer they show an impedance of 2.6 ohms and a DC resistance of 0.55 ohms.
A 3.2 ohm speaker would still work fine. Maybe just a little less loud.
To put a larger speaker in I could possibly extend the control shafts to move the chassis back. Then shorten the brackets between the back panel/loop antenna to keep it in the same position.
Right now I don't think it's worth the effort. I'll keep it as is unless I don't like the sound. Cleaning, fixing the dial, and recapping will come first. Mouse urine covers everything and the variable tuning cap is rusty on top because of it.
The speaker looks brand new, but it has the original part number and is mounted by the magnet yoke so it must be original. I don't know how it survived the attack of mice.
