I found an very old thread where member Bob Lawrence provided a schematic for the Evans FET 500 Custom LV amp. After not receiving a reply to my PM to him, I was sorry to find out he passed away earlier this year. Very sad. My condolences to his friends and family.
Might anyone have a link to or a copy of the schematic for the Evans FET 500 Custom LV? I disconnected the big filter caps on mine to test them and neglected to note the polarity of the wiring to them. I'd be very grateful. |

Grateful for the schematics of the various sections of the amp, but for some reason it does not include the AC line path into the transformer part of the power supply that shows the pair of big blue Sprague 7200mfd@50v filter caps. That's what I needed it for to determine their polarity.
Does anyone have a contact number or email for Derrell Strphens who built my era of the amplifier? |

Thanks for sending, but I do have that schematic page you sent for the power supply card. As I mentioned, I need to find the schematic for or information that shows the AC line in along with the transformer and the pair of filter caps which are chassis mounted power supply components not found on the amplifier's cards.

| Thanks, Jon. But please note my post just before yours. I have all the card layouts and schematics. Need the chassis-mounted parts schematics. |

| I much appreciate everyone's attempts to help me. I left a message for Darrell Stephens at 903-278-5832 yesterday and hope that number is still his and he returns my call. |

Does anyone know if the 2 input jacks are the same? Meaning no difference which one you plug into?
Thank you.

Daniel - Derrell told me the second input is padded by about 10 db.
