OR

Look around hamfests for bad LARGE UPS units
got one which had the powersupply transformer?diodes and Pass transistors
all OK
simple to re do the regulator/crowbar circuit ended up with a 13 volt 30
amp supply
built it on a bread board and had a case made for it
case cost as much as the reworked UPS/ powersupply
hardest job was getting rid of the battery  greenly
