Neither 55 or 56 vac tube radios care about polarity. That's apparently because of the vibrator which drives everything.

The short answer, Yes a 56 Packard radio will fit in a 55 Packard. I am curious why the polarity was switched. Any reason?

Only 3 things care about polarity: ammeter, generator and coil. The generator is easy to repolarize and the coil will work either way, but should have the terminals reversed. The ammeter is also easy as just switch the connections.

Let the ride decide: polarity was changed so cigarette lighter could power things that require neg. ground and for electric fuel pump.
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.

https://www.packardinfo.com/xoops/html/downloads/partslist5556/Accessories.pdf What 55 model Packard do you have? As you can see from the V8 parts book there is a different part number for each radio.

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? Craig
