Gerald;
Need some clarification.
I believe you mean Tritronics..not Tritranics.
http://www.tritronicsinc.com/
Being Canadian..I follow shipping procedures for Canadian Servicers.
I have not contacted the company for a "need to know" .
For continuity..and reference...give the Company a decent shot, if that is
the Company you are referring to.
