Re: Testing 50W amp. Amp current draw?


Thanks George. The test was fast and easy. At 13.8V my old Heathkit wattmeter says 40-ish Watts. Power draw from the PSU was 4.3A (5A is it's limit). I ran it up to 20V but the PSU couldn't keep up. It's a Tektronix bench grade PSU and it's not made for powering a 50W amp. Just for fun I think I'll hook up the oscilloscope and see what the signal looks like.
