All original tubes work. The speaker is blown, so it will need replacing.
I also painted the lettering with Krylon Gold paint. Looks better now.
If anyone has an original speaker for it, let me know.
Heres a video:

It sounds like the cone is warped and the voice coil is rubbing on the pole piece. It seems like those oval speakers were more prone to do that.
An easy, temporary fix, is to remove the chassis and while the radio is playing, press gently on the back of the cone, on both sides to see what side is causing the distortion and try to stick some cotton between the frame and the cone, to minimize the drag. You'll find out easy enough. The so-called shop you took it to, should have, at least, done that.
The speaker is rather special, as the frame is sheared off, on the bottom and the magnet housing must be, drilled and tapped, to mount it on the chassis.
Reconing is a better option.
