Just a quick thought. As previously said (I believe) the A146C has a live chassis, the A146CM (modified?) has an isolated chassis.
This is easily determined from the model number printed on the back cover.
If all else fails (printing illegible for example) the way to tell the difference is the hole in the back cover for the GRAM (record player) sockets.
The one in the A146C is round, the A146CM is cigar shaped. Yours appears quite legible however.

N.B. The cabinet looks in decent condition and the speaker cloth appears to be original.
I noticed that the tuning cursor is right up one end and another image confirms my suspicion that the tuning cord has snapped and will need to be re-strung.
The mains cable is PVC covered twin so shouldn't need replacing, the two looms between the RF and Power chassis (plus the loudspeaker wiring)
are all rubber insulated and will likely crumble to dust when disturbed - replacement is essential for safety.
