Hello to the group!
I've got a pair of ML Monolith III speakers from eBay. Soon as they arrived I found out they're damaged ...
Long story short, at a first check, they were abused with power! Inside each speaker, the internal crossover transformers were damaged, together with the trafo's secondary protections made by Dale's 2k and 50k 50W power resistors installed on the heatsink.
Could manage easy to outsource both Dale's resistors, but I'm having issues in finding a replacement for the transformers, or the correct data to rebuild them in a transformer factory in EU. At a first view, transformers are 1:50 ratio, with two identical windings in serial connection.
Funny enough, one of the transformers is completely burned in, and the other one has a different resistance of one of the half opposite secondary winding (1.6 ohms against the other half of the winding at 18.6ohms).
Any advice and help with additional data about rebuilding the transformers, or a supplier for selling both transformers, would be more than welcomed!
Thanks in advance!
Adrian
