According to the price list from JACMusic, there are C3g tubes with the names of Lorenz, Telefunken and Valvo as well, in addition to Siemens. Don't know if these were rebranded,
There is also another type not mentioned before, the C3o. This is a C3m (20V tube) manufactured for 6.3V usage.
I am reasonably sure that Lorenz, Valvo and Telefunken C3g were all manufactured by Siemens. I very much doubt that there was enough demand for this tube to justify the costs necessary for each of these manufacturers to produce their own version, but of course, I cannot be positive....
While I was watching for a good price on a pair of C3g/s, I thought about getting a pair of C3o. However, the pin-out on these is different than the C3g. So while I could purchase adapters for the C3g (at that time), I would have had to cobble together a pair of suitable adapters, and very frankly, I really don't need anymore projects. lol.
