Title: Biasing for KT77's? Post by: Homebelly on March 01, 2011, 06:13:04 AM Any one running JJ KT77's?
Using the formula in the HRM manual in combination with my terrible maths i figure i should be biasing my HRM MKII to between 30-34mA. Does that seem right? The information i have on the KT77's say they have a plate dissipation of approximately 25 watts. Cheers... Title: Re: Biasing for KT77's?

JJ's are overbuilt to withstand more current as well, which IMO causes more sterile tone at colder settings.
