Default 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
