hi! thanks for the reply's. dr phil there was a typo. i corrected it.the rectifier i put in is 1000v at 25 amps.the amp works perfectly.just having problems with the pilot light.i already put a new light in and it still doesn't work.the pilot light is an exact replacement for what was in the amp. it is a 2150a1 idi 125vac 1/2 watt.enzo as for the test points i am testing from the chassis ground to each of the leads on the pilot light.i am wondering if the high dc voltage blew out the new pilot light.the ac power comes in on a switch the goes thru a 1k heat sinked resistor. then it goes to the center terminal of a triac. mac15a6. from there not sure what happening with it. i get 124v ac on both sides of the heat sink resistor.thought that was strange and the triac reads 124v ac on all 3 legs.the leads from the pilot light go as follows: i don't have a schematic so bear with me.the lead farthest from the switch (120v/240v switch)goes to one side of a resistor. to the - leg af a 330uf 200v electrolytic.then goes to the minus leg of the 4pin 1000v 25 amp bridge rectifier.the other wire of the pilot goes to a reisistor that t's off into 2 more resistors with the top resistor going to the + leg of another 330uf 200v electrolytic.then it ends on the + side of the bridge rectifier.another words both pilot light lead circuits terminate on the outside legs of the 4pin bridge rectifier.i tested the resistors and the all seem ok.this amp is a hair puller for a rookie.i also tested for ac on both wires of the pilot light and got no ac reading.it just reads dc voltage ...thanks phil and enzo for helping me with this. i'm close,but not there yet on fixing this moose.....ed
