tropicalrips 0 Report post Posted January 2, 2004 (edited) i use 15k for led, its just to let know if the amp is on or off so its very dim and doesn't drain my batt my monster is using 2 op-amps, following the A47 design its a Cmoy with a buffer stage Monster A47 variant tread Edited January 2, 2004 by tropicalrips Share this post Link to post Share on other sites

tropicalrips 0 Report post Posted January 2, 2004 the A47 is the buffered Cmoy the OPA2134 will sound better on the Cmoy , more kick then the NJM4556 below is the drawing for the A47 design Share this post Link to post Share on other sites

augustineRS 0 Report post Posted January 2, 2004 Thats a big LED. At least u got it working. Mine had voltage drifting and i gave up on it. Need to work on a new board. My main concern now is actually how to make the casing since i do not have drills but i do have the altoids Share this post Link to post Share on other sites
ahgoh7 0 Report post Posted January 2, 2004 hi! wat's the cost of making something like that?? using a SR60.....does it improve the sound?? noob here.... Share this post Link to post Share on other sites
tropicalrips 0 Report post Posted January 2, 2004 hi! wat's the cost of making something like that?? using a SR60.....does it improve the sound?? noob here.... total cost should be about $30 maybe less , depending on the quality of components u get. it should sound fine on a SR60, but the A47 is suppose to sound better, its design for the Grados Share this post Link to post Share on other sites
