Quiescent current balancing or auto bias?
In my Project 1 amplifier I implemented a balancing scheme that keeps the relative quiescent currents, through both halves of the push-pull, exactly the same. Earlier, I considered auto-bias schemes, such as the Broskie Auto-Bias Circuit or the TentLabs Negative Bias Supply. But in the end I opted for current balancing.
I planned a post on the μProcessor regulated hybrid fixed / cathode bias of my Project 1 KT77 push-pull tube amplifier. A major failure with the high-precision cathode resistors interrupted things. Please do not laugh, I know I had it coming…
Hi there, I just published an introduction page to the series of posts that I intend to release. I first page is just a teaser and a landing page for posts on Project 1.
More to come. Please stay tuned and check in again later.
