I just had my Manley amps repaired and I use 6CA7 tubes with 12ax7 instead of the stock configuration of EL34 with 12at7's Now with the stock tubes EL34 is says bias should be .3MA. When I try and bias my amps after the repair 6 of the 8 get down to about .310 but 2 wont go lower than .416 Is that a problem? the manual says never go past .5 with the EL34s What's your thoughts? should I bring these back to the person who worked on them or is the .416 Ok with the 6CA7's? Thanks Bob |

Think you mean 300mv not 300ma. 300ma would burn up the tube pretty quickly. |
Correct - 300mv, posted on February 16, 2017 at 12:09:07 | |
