I have the same issue, did you find a bridging jumper yet? If so where did you find it?
Krell KAV-500 Bridging Jumpers?
Has anyone bridged a Krell KAV-500? I can't find bridging jumpers. I'm thinking they are just flat ribbon cables with IDC sockets on the ends that pug into J4 & J5 bridging pins on the amplifier boards. If that is the case then I can build them. Can anyone verify this for me or send me a picture of the jumpers?
