When trying to power the amp up all i get is the two input over load light to light up

tested the fets all test fine wondering where i go from here?

Does it produce rail voltage?

mike49504 · 26th December 2009, 07:22 AM

Yes its producing rail voltage positive rail is 39.18 and negative is 37.10

The green power light is flashing

Is the red LED switching on when the green goes off?

Are you sure that the outputs are not shorted? You have to check each one individually.

Are you sure that there are no shorted rectifiers?

Ok there is no green light it wont light at all. the 2 red lights are solid when trying to power the amp up. I checked all outputs,power supply fets, and reflectors all test fine.

Wondering if i can pull one of the legs on the 317 and 337 or is it the 1620's to disable the output side to see if this amp will power up

It would be simpler to pull the two legs of the inductor nearest the rectifiers.

mike49504 · 26th December 2009, 08:07 AM

ok im stupid tonight u said pull the 2 legs of the inductor nearest the reflectors you talking the 2 nearest to the fep16ct's?

Perry Babin · 26th December 2009, 08:10 AM

Rectifiers, not reflectors.

Yes, near the FEP16s and FEN16s.

mike49504 · 26th December 2009, 08:19 AM

ok must be in the power supply cause the amp still doesnt power up and red light are still on

Perry Babin · 26th December 2009, 08:21 AM

Is it producing rail voltage on the center legs of the rectifiers?
