B&K model 466--help needed

[Ray Sieracki]

I need some help, I have a B&K picture tube tester, that has the the tube chart's but I am lacking the set-up book. I am trying to test a 21FBP22A COLOR Picture tube . From what I remember I think you set G1 for 50 volts, unless the tube is marked with an asteriak. The tube charts I have do not list this 21FBP22A OR the 21FP22 it shows on the tube layout. Does anyone have any information on where I can get even a copy of B&K model 466.
Thanks Ray
