Placed an order January 31st and contacted Neil March 3rd. His response was prompt - “26980 tube out of stock. Will ship tomorrow.” The order stays as ‘unfulfilled’. I take it there is a backlog with the manufacturer. As the light (Avaritia NA40SE) is functional I’ll wait it out.

Never got any responses to my bi-monthly inquiries. Probably busy with the GT Micros.
Perhaps this post may nudge him to respond?
