Sorry fellows, but this so called "power supply" is a bad design not capable of sustaining anything above 3 amperes of current, even when a large size computer fan is directed to blow air directly over the heatsink. To advertise it a capable of supplying 6 or 8 amperes could be considered as a fraud.

If you look carefully at the manufacturer specifications, it consumes only 100 watt power at 120 volt AC, which means that it is physically impossible to deliver more than 3 to 4 amperes. The 2N3055 transistor pass regulator does a good work at regulating the voltage at exactly 13.8 volts, not 12 V. But as soon as you pull more than 3 amperes, the heatsink and transistor will overheat, and if you insist in trying hard to extract more that 3 amps, the transformer star to smell burning. If you value your customers, Don't sell them this mediocre power supply.

It is only good for supplying enough currrent for a low powered CB radio, or to feed a low power car stereo, nothing more. (and that is because those consume current on a variying amount, not at contiinuous values. to advertise that this thing puts out 6 or even 8 amperes is a complete lie. Believe me, I'm an electronics engineer, but I was naive enough as to blindly believe the advertised values and ended up purchasing TWO of them... well, I was able to sell one, the other is powering (barely) an old car stereo in my lab.
