Hot Chassis Fix?

I’ve rewired my transformerless sets to eliminate hot chassis. This is the last one I have, but I’m not sure what to do with it. This is an AC/battery portable in which we replaced the original voltage-dropping resistance with capacitance.

As it is now, the chassis is at 45VAC with switch off and 27VAC with switch on (or vice-a-versa with a non-polarized plug). Do I need to address the hot-chassis issue? It’s a small “suitcase” portable, and a small child can easily unlatch and open the back to stick a hand inside.

The other sets were straightforward, but this one puzzles me. What can I do to fix this?
