Anyone familiar with these older Trinitrons. Someone gave me a couple of them, and both look itentical except one has the buttons on the bottom, and the other one has them on top. The one on the left is a KV-27V25 and the one on the right is a KV-27V42. Which one is the better one to keep here? I am keeping the better one for my bedroom TV and donating the other one to Goodwill.
