There are no good ready to go transformer for 6C33C. Tangos are garbage. The 20 years back Tangos were OK for small tubes but Tango is long gone and whatever crap they label by Tango in fact Chinese transformers agglomerate production. Lundahl, with glass core, are very good in my view but they have small core size. At 200mA gap you will have 20Hz but if you build a full bloom 6C33C then you do not want to stop at 200mA. Your voltage is 200V, at 200mA you will have 40W on plate – way to little power, particularly for bass. I do not know the Sowter but generally I would advise to find somebody who would make for you your own custom transformer. Go for 350-400mA gap and for inductance to support 12-15Hz at 20W. There was a guy at my site who ordered one in Europe, I do not know if he like the results – he did not post any feedback. I guess you are American, so you might want o talk with somebody like David Slagle from NY. He is kind of “project guy” and he might be a good source for not cookie-cutter transformers with fast cores. Anyhow, the sound of nay SET is made at 85% by the sound of OPT. If you used any temp OPT to test your 6C33C then you get temp results and temp bass. I do not insist but I think that it is possible that as you get better and deserving OPT for your 6C33C then your view about the 6C33C bass will change. |
