Well since there aren't many post's I thought I would throw one in,I recently accuried my new OTS FM MEM 50 watter,and am loving it . I'am using a new set of matched TAD's and according to the Weber (iam assuming I can use that name here?) bias calculator, The bias should be at around 44.5 mA (hot) . My plate voltage is around 460 does this sound about right,Iam getting the blue glow from the tubes with this setting,but from what I read this is normal? The amp is sounding better day by day,and everything works as it should,I just thought I would throw in a post.Feel free to chime in with any opinions,thanks
