I use this supply for testing or for using it with equipment I don’t yet have a permanent power supply for. I’m testing a Vintage SharP Boombox and I don’t have a permanent 15 volts supply so I’m using this supply as a substitute supply. The supply is just so handy to have around. A little large perhaps but it could be worse.
