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?
Hi Winky ,

Two solutions come to mind ;

# 1 , a small 1:1 transformer to isolate the set from the line .

# 2 , keep it the Hell OUT of small children's hands so no modifications to the radio are needed .


(only partially joking with suggestion # 2 , some things ya just can't "idiot proof" no matter how ya try)
