Vulcan PS Replacement

[Steven Hirsch <snhirsch@gmail.com>]

FYI:

The power supply in my recently-acquired Vulcan GS was serious toast.  Many 
burned-through "flameproof" resistors and at least one of the more expensive 
switching transistors reads as a single circuit node :-).  Capacitors are not 
going to do the trick here, I'm afraid.  (The seller had told me it was not 
working - sometimes you get lucky and sometimes not...)

In case anyone else is looking to rehabilitate one of these, I found a 
switching power supply that will fit the case:

Mean Well PT-65B

Available from Mouser, Jameco and others for ~USD $33.00.  It's a 65W unit 
with +5, +12 and -12 output.  I plan to mount a 7905T regulator (-5V TO-220 
package) on the inside of the case to derive the -5V line.

If I have measured correctly, this is slightly narrower than the original unit 
and has the same length and height.  If worse comes to worse, I may have to 
remove the fuse holder and replace with an internal in-line fuse.

Was able to grab a refurbished and guaranteed Conner CP-3104 from DCP Computer 
Products, so I'm on my way to a working Vulcan 100MB unit.
