Hi, I was putzing around and thought I might do a project with some old tubes. Little did I know that the ones I paid under $1 a while back and put them in a bin could get scarce now. Prices today were from about $30 each to $85. They are Nuvistors from early Russian (yes I know we are not real happy with the now) military. The type is 6C52H-B. What I was curious about was the logo. Who made them? Anyone know?
