I have a fender hot rod deluxe. I read an article about swaping 6V6's in place of 6L6's. I changed the screen resistors as recommended in the article, but the article makes the following statement:
"6V6s also have a greater plate resistance than 6L6GCs, so there will be an impedance mismatch. It won't be enough to cause damage, because 6V6s draw a lot less current than all 6L6s, but if you plan on permanently using 6V6s you ought to install an appropriate output transformer. A high pass filter is created between the plate resistance of the tube and the inductance of the output transformers primary. In other words, installing 6V6s is going to cut a fair amount of low end."
So my question is: Will continued operation without changing the OP TX cause any damage? I'm guessing not, but want to be sure, as I love the sound of the amp as-is.
Thanks,
