    hello im new to this forum. i have had this lab volt model 189 power supply lying around for quite sometime now, i used to use a radio shack power supply 4 amp, it used to work great but now its time for the bone yard for that one, anyway the question i have is for the lab voltit only has 2 amps. on the 12 volt side, i was wondering if anyone knows any mods for this power supply to make the amp's go up to say like 15 or more amps. i would like to be able to test car stereo amps or cb linear's, i know 15 amps isnt a lot of amps but just as a ground base mainly is there a way to make the amps higher. i know the power supply is very old and old but i like it
