[Premium-Rx] New CRT for HP8753A Network Analyser

[John Miles]

You can always open it up and add a turn to the HV transformer's filament
winding.  That'll bring the brightness up substantially, at the cost of a
big portion of the tube's remaining life.

Failing that, try Tucker Electronics at (877) 667-6044.  They sometimes
offer surplus HP CRTs for sale.  Also
http://www.sphere.bc.ca/test/tubes.html is worth a look.
