Subject: Monitor colour guns misaligned

Can anybody give me advice on how to realign the colours on a couple of my
monitors?  They are Microvitec Cubs in a Torch cheese-wedge enclosure. The
Red, Green and Blue colours no longer align with each other, giving very
strange colour effects.
 
If you display three lines of primary colours, eg with
VDU 129,157,10,13,130,157,10,13,132,157,10,13 in mode 7 to give a red,
green and blue band, you get the following effect:
 
+--------------------------+
|  Band of red colour      |
++-------------------------++
 |  Band of green colour    |
 ++-------------------------++
  | Band of blue colour      |
  +--------------------------+
 
The red gun needs to be nudged right a bit, and the blue gun nudged left a
bit.  Any suggestions?
 
Thanks
