Svetlana Winged C 6550's always had had a great rep', they are NOS these days, and there are some factory seconds floating around that need to be avoided.

If you want something better than modern offerings and don't mind spending a tad bit more $, maybe look at 60-70's NOS units from likes of RCA, Sylvania made in the US. The 6550 is an American made tube and some of the best 6550's have naturally been the American offerings.

Thanks @F18 I'm being searching but either see Chinese and Russian made only...

If you email VTL ask them if you can use the KT88 tubes, or others in the  KT series.

He will most likely be able to use the KT88's without any dramas as they are spec'ed similar to the 6550 with higher plate dissipation. Other kinkless triodes I would avoid being substituted for either kt88/6550.

These days those valves are ONLY made in China and Russia. Any USA (or other country) manufactured ones are all from the past.
