Re: Vortex power supply - AC, but can take DC?

[Dan <danielalbertini72@yahoo.com>]

Guys honestly its only a matter of time before you burn something out!  I 
have been round and
round with my fellow repair people and we all say the same thing it is not 
worth the risk and time
involved to get the equipment working.  These are the most experienced 
people there are saying
this, four of the electrician/repairperson friends used to work for 
Kustom/Legend in Chanute
Kansas now Ultrasound !!!  They modded the big dogs Super souped up 
Fenders/Mesa Boogies.  It
seems like you are saving money but in the long run it costs much more and 
often left us with
unrepairable by conventional speaking standards goes equipment...  Buy the 
proper adapters from
the companies or what they recommend :o)
      Happy Christ mas Everybodys and let it lead you all into more JOY 
for the new year, 
      Love and Light to your loopy delight AGW Albertini "Custom" Guitar
