Man...I'm at a loss to come up with an alternative solution. Maybe you could communicate to Spectron that if they can't help you given you live in New Zealand and the costs associated with their method of repair are untenable...why would anyone in New Zealand want to own a Spectron product? Spectron upgraded my amp and I found the Customer Service dept. quite accommodating. There must be an approach here that provides a win-win for you and Spectron. Good luck!
