I hope someone can help me Please

Hi, I hope you can help me please. My brother passed away and left me a collection of old phonos. He was a RCA repair man in the 60's -80's . He loved the old phonographs. He wanted me to find a good home for them. I have no idea what they are worth or who would buy them. Could you please steer me in the right direction to find a good home for them. There are also many 78's.  Also a lot of parts and his RCA repairman tool box with tubes. They are in the Bronx N.Y.. Here are some pictures. Thank you very much and have a great day!
