Almost as much as 5691 which also should be non microphonic. The 5691 tube was built for rockets so it could withstand something like 200Gs.
I thought the 5691 and 5692 were built mainly by RCA as a long lived tube but did not have the incredible internals of a Bendix with their ceramic spacers eg and Nonex glass etc.
Actually 5691 and 92 were made mostly by GE for RCA. I guess they had the excess jigs to make them. And not made to the standard of the Bendix tubes, but way above the needs for an ordinary 6sl7 with 10,000 hour lifespan if recommended specs were followed.
