Aid is over 7 years old, has had a recurring problem with the tube “spinning” where it attaches to the aid. Has been repaired 3 times by Costco, once under warranty and twice for $129. This time they won’t repair it because it is over 5 years old. I know how to replace the tube and would like to do it myself. I’ve found an online source for $75 but I don’t know whether to order the or the HP version. Found the size (3) on the old tube but can’t find the power designation. Don’t want to ask Costco because the manager wants to sell me the Forte 8 and will really annoy me if I ask! If is an NP but I order the HP will it fit?
