Hello everyone,
I got this diy rack for Danner cassette format, I bought it used with 2 BFE eq modules in it.
After a couple of years of use the eqs showed some problems and one of the two stopped working, I sent them to repair and I was told that a lot of transistors and other components inside the modules were damaged and it was a difficult repair.
I'd like to understand if the rack is the cause of those problems, so I know if I could use it in the future with some other modules or send it to repair, The only thing I noticed in use is that when I turned the power off the ">18dbu" led on the eqs blinked like they received a spike of volts while turning off, apart from that the eq worked.
I attach some pictures here of the rack and the power supply if anyone can help me understand, thanks![IMG_20230515_105059.jpg IMG_20230515_105059.jpg](https://cdn.imagearchive.com/groupdiy/data/attachments/60/60908-02aede6e871ba95d6fa24929cefdcee7.jpg)
