I have 4 tubes that I think are rectifier tubes, 4 pin octal base and look like it. They are marked with CG2C (the "G" is the Russian figure that looks like an upside down "L").
Anyone have any more information? I knew what they were equivalent to when I bought them, but with my glacial pace of DIY project advancement, I have long since forgotten. My guess is that they are similar to some very common rectifier, but help before I blow a few up (at least I have 4...)
