got the schematic from poly tone.i have to figure out how to downsize it.i found out that i have the - 15v supply ,but lost the +15v supply. if i touch the regulator it gets hot.something is loading it down.i have the +24volts at pin 1 of the pnp regulator.any suggestions on locating the short that is loading down the regulator.i only get .003volts going to the ic socket of the +15v.the -15v is present. i replaced the regulator and got the same results.now how to find the part that is shorted and loading down the circuit.Roly,enzo,and juan ,i am going to leave my e-mail adress.if you want a copy of the schematic i will send one to you (polytone taurus elite).i have the power supply and another print with everthing else.the only problem is the print and the circuit board numbers don't match as they use the same circuit board for all three channels,but it does allow you to go part by part thru the circuit.....edwardeffect1@yahoo.com....thanks...ed!!
