50 Amps all Day and all Night from a linear supply. Heavy duty supply with a 100% duty cycle. A solid supply with engineering problems for the ham operator. Engineered with a bad ground loop. Forget the battery and a second 277. Remove the resisters in the ground leg and strap the Negative terminal to the chassis ground. If you are afraid of or don't know how to do this; one,(and only one) radio can be operated from the as is condition of the power supply. There will be 3 volts Peak to peak of RF from a 100 watt radio on the 13.8 volt line. Under these conditions don't try to power anything else. I strapped the ground to the chassis after removing the ground resisters. Then, I drilled a hole through the face plate to access the output voltage adjustment which I set at 13.5vdc. E-mail me for details. KC3Z drogers@comcast.net
With the ground resistors removed and the minus/ground strapped together this is a great linear 50 amp supply. Expect NO support from Audio Authority. They just don't respond to any e-mails. Dean KC3Z drogers127@comcast.net
