The triac is the Achilles heal of this device - All parts etc are obtained from THERMO-ELECTRON CORPORATION ,UNIT 5, THE RINGWAY CENTRE
EDISON ROAD ,BASINGSTOKE ,HANTS ,Telephone: 01256 817282. There is a guy called Nigel Lilly in Service who has been working on these devices for over 20 years and if he can't help you - no one can.
