All research I have done online seems to indicate that this is a safe swap that will not damage the amp transformer, etc. However, there is a possibility that the power transformer is robust enough to handle the extra current, but not quite robust enough to supply enough current to cook the output Re: SE 6L6 VS parallel SE 6V6 « Reply #10 on: February 21, 2020, 04:56:53 pm » If plate and screen voltages stay similar/same, 6L6 6V6 EL34 will all need very-similar drive.
