Default Hafler P1500 power switch replacement help needed


I am very glad I found this forum & am looking for some help.

The AC mains switch on my Hafler P1500 has died. It is a SPDT rocker switch with a green led in the button. I have tried to find a direct replacement for this switch with no luck. The closest I came was by contacting eswitch, but the switch I need is a non stock item with a 3000 pc minimum order!

I did get a couple of similar switches from Digi-Key, but am not entirely sure how to connect them as the order of the lugs are different on the switches.

My question is, can I wire up a switch with no illumination, to this amp? I can't find the schematic to determine how that led got power from the amp board. There are 2 wires coming off of the transformer connected to 1 lug of the old switch, and then a black, and a white wire connecting to the other 2 lugs. The black & white wires go to the amp board, and are not labeled as far as I can tell.

I would greatly appreciate any thoughts or advice that may help me get this amp working again. There are no resources available I could find for Hafler service anymore since the company went out of business some years ago.

Thanks very much!
