[ICOM] PW-1 Power supply.

[Larry Young]

Dave, the AB4OJ web web site has information on repair and upgrade info on the PW-1 power supply. I would caution you if you have no experience with switchmode power supply repair and the necessary tools and instruments, that you may want to seek qualified assistance.
Good luck, 

Larry K4LXV
