I have a large mixing console that uses a Pair of LM317K TO-3 type Adjustable V-regs for the +/- 17V rails. The mixer draws about 1.25 amps from each rail. pretty close to the 1.5amp rating of the 317K device.
I need to replace both regs as a power spike killed them. So i am wondering before i place a purchase, if there is a drop in repalcement rated for a bit more current?? maybe 2 amps or so just to increas the margin.
Early revisions of this supply had a pass device for each side as well at the 317K but at some point they revised the supply and took that part out and changed the board.
