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

the A47 is the buffered Cmoy smile.gif

the OPA2134 will sound better on the Cmoy , more kick then the NJM4556

below is the drawing for the A47 design

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 tongue.gif

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
