Yes, a computer tube version of 12AU7. They had special cathode processing to avoid "cathode poisoning". In logic circuits, the tubes might spend a lot of time in a non-conducting cut-off situation. Apparently, that can cause emission loss pretty easily with typical cathodes.
I happen to like 5963 very much for audio, but I've never tried the RCA. I have some CBS and Sylvania that are very nice.
