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 Cool . 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

44.5ma isnt too terribly hot for 460 volts; it's right at 70% which is nominal for most amps, a little warm for typical D Style sounds. 35.86ma is 55% which is typical D-style settings, but if you are happy with how it sounds, go for it! The blue glow is normal, especially in higher plate voltage amps. As long as it doesn't red plate and sound like crap, i wouldn't worry about for now.
