The original parts proved to be defective (leaky) and their replacement cured the powering offset tuning problem of my SONY STR-6055. 😎 😎 😎

Now back to your original subject : lowest noise transistor quest, @saabracer23 !

Nice work! Oh I’m past that, now I’m working on some issues with my own tuner. I’ve been doing a lot of reading and have found that this tuner and some other early Sony’s are problematic. Having issues with MPX board. I started a thread going on it, need to find a decent replacement for the jfet, 2sk23.
