Craig: All I have read on the old cars was that radios are polarity sensitive, However this wasn't about Packard radios, just radios in general. I do remember from MANY years ago radios had sticker or label telling for Pos. ground only or neg. ground only. I was assuming Packard radio was polarity sensitivity.


All I can tell you is that I converted my 55 Pat from POS to NEG ground right after I bought it. The AM tube radio worked before and after, although the main reason I changed to NEG ground was to install a modern (NEG ground) CD/AM/FM unit.

Maybe the PN change has something to do with "Wonder Bar" vs pushbutton-only?
