Can a broken leg from a tube be soldered and used?


I received used 6C33C-B tubes, but one of them has two legs broken. Can the broken legs soldered and the tube can be used again? Or, would I rather purchase a new tube?

This tube looks odd. It is such a bid body, but the legs are just same size of small tubes like 12AX7.

Ihcho, This is the first time I have heard the need expressed for matched sets of 6C33C. This is a tall order--particularly as these types have a relatively high failure rate during use, which further complicates consistent matching.

@$15-20 from Eastern Europe does it for me.
Ihcho, I have been through many retubings of VK75SE without matching. From the owner's manual: "...implements a sophisticated autobias circuit that automatically compensates for tube aging and line fluctuations, as well as marginal mismatching of tubes." Moreover, IME in BAT amp these tubes deteriorate sonically after 1200 hrs. The improvement gained through frequent retubings is likely greater than the effect of scrupulous matching. Finally, for what you propose to pay you could be making dramatic mods to that unit.
