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

I once purchased matched pairs of 6C33Cs from BAT for use in my Atma-sphere amps. You might check with Victor Khomenko, if you live in the US. Any extra cost was well worth it, since the first set of tubes have lasted nearly 10 years with no failures and all still bias well. As to the repair job, yes I think it could be repaired and a proper solder joint is not going to break off in the socket. The bigger hazard is that heat from the solder gun could cause a fragile internal wire to go up in smoke, causing a short. I would opt to throw that tube away.

Dgarretson, do you mean that 6C33C-B tubes do not need to be matched?

Lewm, how much did you pay for? Over $100 per piece, right?
The tube tubes will be used with my vk60.
I guess new sets of 4x6C33C-B and 8x6SN7 from BAT would cost me at least $600, right?

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.

Dear Ihcho, It was several years ago that I bought the 6C33Cs from Victor. I bought two sets of six matched pairs each. At that time, I think Victor had the inside rail to obtain tubes that had been built in the Ulyanov factory in the early 90s. Those are said to be the best run of 6C33Cs. I either paid $80 per matched pair (i.e., $40 per tube) or $100 per matched pair. I really think it was the former amount. But bear in mind that this transaction might have taken place as long as 10 years ago. Anyway, since you have a BAT amp, they should give you some sort of deal, but it would have to be based on current values. You have a high-end amplifier; why compromise on the output tubes? They will last a long time.

Ihcho, A belated question. How long are the stubs on the damaged tube. If they are long enuf to make good contact in the sockets that may be good enuf. The actual contact area is usually closer to the glass envelope than at the base of the pins. FWIW.
