Re: Tektronix 465B Scope - Some problems.
OK somecrt shots of a warmed and running 465B
First is a dim focused spot, then a brighter one. These tubes are not as fine at focusing as my HP1740 and a far way from my old HP180 frames, but the 465Bs are nice usable scopes and I have a pair of them in working order.
Next up is the anticlock extreme of the focus control giving a sort of barrel shape. finally the clockwise extreme giving a disc.... and you can also see the mesh being imaged.
I was using an Elicar 90mm macro lens, so they each cover only the centre four squares of the crt.
And my spare 465B produces similar spots.
Hope this helps a bit,
David
