hey ram, which software i should downlaod theres alot of software in ZEITNITS  i dont know which one

the trouble in my xr71 pro its not wotking i bought it from ebay ebay pre assembled, the first time i turn it on after i assemble everything its sounds continously and no changes in any potentiometer when adjusted, this is a coil attached coil used is 3.2 ohms, 28 turns #20 awg, i tried to remove the coil whith the sound, and the xr71 still sounding and has no changes when potentiometers adjusred. i used a 12v , 7.0 Ah battery. i folloowed all the sellers instruction instructions but evrything is no good. he should have tested it before he sell his item. now im waisting alot of money trying to resolve the problem of this xr71p. now i bought alot of electronic parts to replace the parts of xr 71 one by one. to find out the which component is not working., but i allreasy check the voltages in ic's its all 10.6 but wierd its supposed to be working may be some parts are not working or reverse or may be by tyhe values of components. i am losing interest to make this work may be t will end up to my junk what a waste of money, i should have bought a working unit, for $700.00 i should no problem now

i am thinking building the delta pulse unit i think its more better to start there atleast i can learn step by step parts to parts . what can you advice which delta pulse is working good, how el bombaci DP OR EUGGENE DP

its doublesided pcb the on the right from your attached filed with the pots, my IRF it gets hot but i turned of the power immediately to save the IRF740 i also replaced it with new one 4 times but still gets hot, ami still able to save my IRF?

i removed the transistor goinf to the speaker and test it OK, but when i resolder it, has no more sound. i removed the IRF and place in the big heatsink to make sure it wont get hot again, i also removed the capacito 4700uf and clip it on the wallside of the box.
