Title: Pin Voltages per Nik + Bias Calculator for Tube swapping Post by: mx on December 10, 2008, 08:30:31 PM Hello,
The attachment on pin voltages is a reference for builders and trouble-shooting. I haven't found this info elsewhere on the site when I needed it so here you go... The link below is from Weber Speakers and great for determining bias voltages when changing tubes. I noticed a big voltage drop when I swapped out the JJ's for some GT 6L6GE "clear tops" which required a big change in bias setting. http://www.webervst.com/tubes1/calcbias.htm Matt Title: Re: Pin Voltages per Nik + Bias Calculator for Tube swapping Post by: mcinku on December 11, 2008, 08:48:18 AM My plate voltages are slightly higher than yours...
6L6 454V V1a 195V V1b 204V V2a 210V V2b 213V PIa 318V PIb 301V I use Tung-Sols all over ;) |
