Hey Brazzy, Thank you and Happy Thanksgiving for you !
I am from Switzerland so we do not celebrate thanksgiving ;)
I have changed power transformer and relays on mine. I like my DT amps , they are amazingly good !!!
It seems to be a business problem more than a technical problem. All manufacturers prefer to sell you multiple systems than an all in one. non sense for us but not for them...
My amp was in perfect shape and suddenly after 2 hours of playing at room volume, the transformer died when in stand-by mode.
250$ for the transformer as spare parts in Europe.
