WOW! Those were fast replys! Thanks for all of the info, Mark and Ed.
I would need this power supply for an extended amount of time (months!). And, as I often get called upon to supply sound effects (telephone particularly, for some reason) I would probably go ahead and purchase one, provided I won't have to remortgage the home!
I will post on the forum you suggested, Mark.
Thanks VERY much, guys, you saved the day.
Sincerely,
Rich A.
