RE: Amplifone won't focus!

Check the wires going to the focus control. One or more may have come
loose. If not, try replacing the wires or focus control.

Subject: VECTOR: Amplifone won't focus!

Hi ....

I've been putting an Amplifone together from parts acquired from ebay
and
elsewhere, and tonight I got power on for the first time.

The HV board is giving out a steady 19.5Kv with the HV cut-off set
around 21Kv.

When driven by a space duel PCB I cannot get the picture to focus,
turning
the focus control on the HV board makes no difference at all.

The convergence is awful as this has not yet been done on the tube ...

Now, given that the HV board has a 'red is dead' HVT how can I determine

the problem? AT this point it could be anything as all the components
I'm
using are untested!

Thanks!
