Replacement tubes

Does anyone know where I can buy replacement tubes for Oticon Duals on line? Mine are through the VA and it takes over 2 months to get service.

i hope the replacement for the A700 is a decent price, or im gonna have to aim for the A550 as an upgrade for my A200…

what does this have to do with my question?

I emailed them about some tubes that were not listed on their site. They promptly added them. I think they add items as requested. Seem to be nice people to deal with. They came in a few days.
