If you are looking for original USA built BozaK mixer advice the person to get a hold of is Buzzy Beck. I have emailed him on several occasions and he will advise you on repairs or help with mods to the mixers for usually no charge. He actually does the cue/program mix modification for the headphone output that sounds like what you are looking for. Many people here on wave have dealt with him and find it nice to correspond with someone that passionate of what he did for over 50 years. If you are looking to do mods etc. on the newer imported Bozak mixer from analog developments you should contact the guy overseas from audio for the soul. I do not know what kind of luck you will have with that but it's worth a try. When it comes to Urei I understand that Mario repairs and does mods to a lot on them. Happy holidays to all.
