triaxis troubleshooting

[dgzieg]

Hi, I've got a problem with Lead 1 green on my (serial number T1484, v. 2.0) Triaxis. In this mode only, Lead 1 drive doesn't have any effect. A very, very low volume level (compared to all other modes) is present, all other controls function (you can hear them changing volume or tone), just not Lead 1 Drive for this mode. I have swapped known good tubes in and out, plus the other modes of Lead 1 work properly. Can anyone point me to a component or area that is specific to this situation? Thanks for any input.

Check your ribbon cables or look for any broken wires inside. If everything is good you might have a bad LDR.
