I did some looking here, but could not find anything on the F50 bias pot mod.

Could someone please post a link and or pics, I wanna have this done asap.

I'm not using boogie Chinese tubes anymore, I just changed tubes , and for a third time the amp sounds totally different than the last 2 tube changes.
I'm gonna bit the bullet and buy an octet of Winged C's.
