No, if you want use two single OP instead one dual, use two TL071 instead one TL072,apex, can i use 741 op-amp instead of TL072?
coz i'll try to incorporate step-driver using an op-amp and the main amp on a
single pcb

mane go alexan if you go to manilathank you so much...
mje's are nowhere to be found in our city... thats why i settled on using TIP's
but still thinking of H900....
i'm located at Iloilo City, an hour of plane flight to Manila
i'm afraid we cannot build h900
but instead build b500 with tlo72 step driver all parts available
regards
oh sorry... i mean two 741's, got 6pcs. of it and thought i can use it instead of tl071.
741 can't be used, use TL071 it's not expensive.oh sorry... i mean two 741's, got 6pcs. of it and thought i can use it instead of tl071.

You must use MJE15033/MJE15032 for H900, but with B500 at lower rail voltage there are many TO220 drivers.
