Tubes 6L6 or KT66

Mike Simpson · From: Gilbert, Arizona, USA

Does anyone know the differences in 6L6 and KT66 tubes? The stuff that I find on the internet says that they interchange. Does the 6L6 have more output? I have 2 amps and the one with 6L6's is louder and does not break up as soon. I know... I should just switch them between amps and see what happens but I thought I would ask if anyone knows the difference.

Thanks,

They are similar, but not the same.
You should really only change power tube types in your amp if you can re-bias your amp for the new power tubes . This may also require changing bias resistors as well for max. efficiency.

Tube amp circuits are designed specifcally for the type of tube that is used..can you swap ? yes..should you ? Not sure...

It's like Elaine says on Seinfeld..

"They're exactly the same, just different"

try this link, it may be of some help..
