Is Channel Balance 20C Stamp Code same as 2030?

A professional from Aichi Pref., Japan says:
I would like to replace old channel balancers which are indicated "20C USB" on. Are they "2030" at your product? Please let me know the mean of "C". Thanks.

Thanks for writing in. You are correct! 20C is equivalent to our stamp option of 2030. Keep in mind that this only indicates the stamp option you need to select for your balance, but not the balance's identity itself. If you need help identifying the right Series of balance to replace your old hardware, send us photos of your old balance. Let me know if you have any other questions.
