Yikes...not again!
I brought this banged up unit from the US hoping that I could do another save.
The unit had a blown right channel output. A couple of resistors looked tired. They got changed.
I recapped ONLY the power supply for now. I then dismounted all the main outputs.......proceeded to power up on dbt.......bright then dim......BUT, R52/54 get hot and smoke! These 2 resistors are only connected to Tr16/18....they get hot too.........any ideas?
I tested ALL the tr's on that channel before doing the above. As a main out put did blow.....I changed the 2 main drivers to ksc2073 / ksa940 ......the originals tested ok.
