Re: Re: VECTOr: Re: vector: 25" Amplifone tube DAG connector/spring?

The large coil part of the VECTOR HVT should look like this (when viewed from
the top):

The RASTER HVT looks like this:
----------

But considerably more pointed. The one pictured opne ebay is most likely a
raster, or Amplifone made a very small run very late.

Then part# of the one on ebay doesn't match the raster or vector manuals.

IMHO it's a raster. But, I could be wrong. Either way, not worth the chance. I
do have both the vector and raster monitors her.
