The 10BP4 should be OK , I had some dull raster , and that was with original caps in the set .

Any ideas ?

I don't know about the B&K 400, but my 465 doesn't use an adapter for the 10BP4. I would expect pin 6 of a 12 pin base to be used for G4 if a CRT has one. G2 on the 10BP4 is pin 10.

I'm not sure what it means by open. G2 should have infinite impedance so open would be good.

I have trouble with the socket on my 465. On some tubes it doesn't make contact very well.
