You briefly mentioned in one of your videos...they might work in the Muzishare X7. I currently using Shug KT88z..but am looking for a warmer/different tube. I saw a post on a forum where someone recomended EL34 with the bias changed from 40ma to 28-30ma. Is this a safe thing to try?
Thank you...love your vids!
It should but honestly I never tried biasing up EL34 tubes in that amp. It's possible the bias circuit would need to be mod'd to work with them? This chart will help you figure out what bias point to use, I'd shoot for 60% bias on the class AB fixed bias line.
