Default Stasis 3 - one channel burned

New member, so please bear over with me.
See below photos - any ideas as to what has happened and if it is an easy fix/replacement?
Schematics for Stasis 3 would be helpful too.

I suggest you to send a PM to our member "tiefbassuebertr" who seems to be very well informed about Threshold products.

Some more knowledgable forum members will chime in and most probably be able to provide schematics as well.

In the meantime I would suggest to take better pictures as you will be asked for anyway.

You will have to get better acces to that channel PCB as well if you want to troubleshoot that amp.

with plenty of big and good lit pictures , we can try to help you , but having minimum praxis in electronic is a must

Both times my old Nad 3150 has failed (smoked) was caused by shorted caps (electrolytic). When this happens it can destroy some transistors and resistors. Now most caps has been replaced......it is a 35 - 40 year old amp now.....most electorlytic caps does not like to be more than 40 years old.......

Now that you have the schematics, perhaps you can indicate the parts that have
been damaged? Hopefully it'll give an indication of what went wrong.

OT: Presumably those Threshold schematics were hand drawn. They are absolutely beautiful.
