Biasing my Einstein. I can't find the trim pot?

[tripstan]

Well I'm biasing my amp for the first time. I followed directions on a youtube vid and from Diezels site and having no luck. It's made late in 2008, Dec I think so the post are located in the outside of the chassis. When I stick the screw driver in the bias pot and it's not connecting to anything. I can read the mA I just can't adjust it

i think the small red and black holes are for the multimeter, the bigger black hole (behind the red one) for the bias... you'll need a long and small (i guess around 2mm wide) insulated, -screwdriver.

Thanks I found it Tuesday morning. I don't know if it's because they are just new tubes, but the KT77's are awesome. The old EL34's were baised hot (probably just drifted) 82 mA, it sounded good but the new tubes are bringing a smile to my face.
