B&K model 466--help needed
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

I have a 467 here, and a 466 at work. Both work very similarly, so I think you are basically right. Set the filament at 6.3V, G2 at minimum, and G1 for 50 volts (I checked my 467 book-it does not have the asterisk) in "setup" mode, switch to "cutoff" mode and turn the G2 up so the meter moves up one "tick" on the scale (if it does not move and the tester has a G2 switch, switch it to "high"), then switch to "test" mode and see where the pointer goes. (Switch the R/G/B switch to each position to see all three guns.) I hope that is enough to get you going.

It may be different on the color tubes but the G1 is set to 45 volts on the B&W tubes, there is a green line marking it on the dial scale.
The G2 is set one small division above zero.

B&K has the data online:
http://www.bkprecision.com/downloads...etup_Chart.pdf I just googled "B&K G1 CRT" and the above came up in the search results. Sometimes Google is your friend!  Cheers,

My 466 instructions say to set G1 at 45, G2 for two small meter divisions.

B&K model 466 help
Thanks to everyone, I got thru with this 1st test, from all your help. It was interesting and informative to find alot of information. I looked at the B&K site, looked at all the update's. The 21FBP22 looks real good with real good emision's test on all guns. Just to verify I will be trying another tester for comparision. I found several instructions for sale thru different sources,from $17.50 to $29.00. I am so happy to have asked here and got the help I needed, especially with this normalize control that I was not quite familar with and get jumped started with the testing.
thanks,Ray

Thank you for posting that. I am going to save a copy and put it in my 466 box at work.
