Thought I'd bump this thread to the top because Bob's done a couple recent reveiw videos on this set. I've been finding it very fascinating because I picked up this sets bigger brother earlier this fall. Basically it's the same chassis but with a 19AP4 CRT. Originally I picked up the model 425-CV because I was in need of a good 19AP4 for my DuMont RA-119. But the more time I spent researching the Sentinel, the more I wanted to keep it complete. Recently I finished restoring the chassis. The cabinet is in decent shape and only needs a little touching up. I currently have the chassis back in the cabinet and have been watching it over the holidays. Turns out it's a fine performing set.
