Hi Shari...
If you got some defective 6C33 please let me know as we stand behind our tubes. That tube is impossible to test in traditional testers, as they draw so much filament current. And most people don't need them matched...
But I paid the gentleman that does our service and repairs to have them tested one by one in a custom built amp, that way we would have them matched. There is one amp that does need them matched...the Panther (a beast)...so we did a slew of them.
The old Russian 6SN7 have been a hoot. They are 1964 vintage, and I picture Kruschev pounding his shoe on a desk while these were being made. I don't know if you read the docs that came in the box....what a time that must have been. They sound great, and will not give you a lick of trouble.
