New to DIYAudio

Hey all. I am new to the site and newish to servicing Class H Crowns (DSi, CDi,XTi). I work in digital cinema service and got into fixing Crowns as an extension of the service. I am hoping to get advice on more advanced servicing of these crazy amps (very complex) and pass along any info I might have on audio (Dolby certified in ATMOS design and set up) and Crown repair, or anything other related stuff.
