I was trying to sort out a couple of cooked ESC's today - long story short, I called Novak for confirmation on an old ESC I wanted to check.
For 100% confirmation on the type you have, look on the underside for the barcode sticker inside the unit. Underneath the barcode is a Alphanumberic number. Call Novak in California on
00 1 949 833-8873
Option 1 for customer service - Give them the number and they'll tell you which it is.
