Hey Kevin,

I don't know about DJ but I have an old Lanzar 600-S car amp. According to Lanzar, it delivers 540WRMS into 4 Ohms per channel!!! Sorry no pics but there are 12 MOSFETs, 6 per leg, driving the power supply. (I know because I had to fix it) There are 11 output transistors per rail, if I remember right, TIP142/147's. I haven't measured B+ and - but the filter caps are rated at 63V so I assume 55-58V rails. The heatsink measures 9X19.25X2.5 inches. It weighs, I'm estimating, 10-12 lbs. This thing is a Hoss..... Since I repaired it I have only put power to it to see if the pwr supply would hold up. It did but I haven't put a load and signal on it.... Who knows, it may blow up again..... It's a really old amp probably out of the late 80's or early 90's. I know DJ has said a lot of things but I wouldn't be surprised if he did come across an old amp, especially if he has a buddy in the repair or junk business. 15A output? I kind of doubt that also. There's only so much current that an amp needs before you hit the rails anyway.......... I'm not saying it isn't possible but I find it hard to believe too. 15A INPUT, yes, I see that easily, as these power supplies aren't that efficient.
If there are any typo's sorry, my ferret is helping.

The best audio is clean audio!

u can try 4191 also.it is rated at 50 w per channel.and costs the same price.
please let me have ur mail id so that i wud be in a position to post a schematic of the circuit.

Hello buddy could you please send me the schematic of bridging stk ic to my mail id : phoeniix9@gmail.com. Thanks in advance.
