Need Help Replacing a 240v Mains Transformer - RESOLVED
crwdns2934249:0crwdne2934249:0:
So I need to replace the mains transformer in this amp. It is a 240V primary power. The new transformer wire colours do not match the schematic I have and I am having difficulty identifying which wires on the primary side go where. I have the secondary side nutted out. Appreciate some help with the primary side. Cheers.

Hey guys - I contacted Hammond - the maker of the transformers, and he gave me an updated wiring diagram. This coupled with a mate working out which primary wires go to which jumper sorted the problem and the amp and its new transformer are on speaking terms. Big thank you to all who contributed to this thread. Cheers, Rhea deLascy-Wells.
