Well, did that.
Did not want to come out. Those tabs were seriously grabbed by their sockets.
I took a large flat screwdriver and raised each corner several times.
Eventually I dislodged the left corner, and then after 3 more minutes of harrassing it the right one.

The right has some white stuff iniside; I wonder if someone tried to glue it.

The chassis was repaired recently, with all caps replaced, lytics and film, with modern orange dip types.

The guy who did it obviously can solder, the rework is neat.
He left the antenna cap in a Philco tube, as it is on top and so is visible, it is probably restuffed as the tar is not what you see in originals, it is black and cracking a bit.

So, I will check it against the sch, and if it is OK, will try to power, and, should it work, give it the alignment.
