<div>Could I use *any* MC7805CT as a replacement, as the first link shows different models of that regulator? Some models of the regulator have variable output as listed in the second link. I suspect the output should stay constant for power, but since the amp output section has the pot on it, was wondering if I should go with the adjustable output regulator or just stick with a fixed output?</div><div><br></div><div><br></div><div>Brian</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div>
