Yes it is. It allows ten plus supposedly give better operation on 15.

Could that be the "upgraded" board to allow 10 meters?

I took a look at the input filter board and it's not an 81763. It's labeled as an 81550 but it is not loaded with the same components as the spare 81550 that came from the seller, nor does it match the 81550 in the manual.

I thought maybe the 81550 in the amp had modified to be an 81763 but the documentation for the 81763 says it should have two coils and 4 caps. The one in the amp only has one coil and a resistor in place of the second, along with only one cap.

Anyone have a clue what I'm dealing with here?

I've been ignoring an input SWR problem on my Centaur for a while and decided to take a look at it today. 10 and 15 are higher than the others, (about 1.8 to 1) The others range from 1.1 to 1.3 to 1. Is that typical? If not, the 81763 10/15 meter optional filter board seems to be a likely culprit, but there's not much circuitry on it.
