It's not down to your level of competence, it's a matter of type approval. This radiogram satisfied electrical regs at the time it was made, and inherits grandfather rights today. If you modify it significantly, it will need to satisfy the regs in place *now*, which is a real can of worms.

It's obviously yours to modify as you wish though.
