Help with Theta Ds Pro Gen V


hello guys,

i am trying to repair the dac that has a very distorted output.
opening it i found that the transistors at the output were changed in both channels.

as it is impposible to find the original scheme, maybe for me wuold be important to know the exact model name of the last transistors at the output.
Is there someone who can help me?

Thanks a lot

I would try Theta. Otherwise, if you do a google search for the unit, click on images link once the search is complete. Sometimes you can get lucky and find that someone has posted schematics as an image file.
I would Email theta. Diy forums have very few info about their products and how to service/repair them.
Theta stopped supporting all legacy products after the company was sold several years ago. I am the original owner of a Gen Va DAC that fortunately still works.
