Neve 33609J


Dominick Costanzo:
I've a Neve 33609J that regularly has an issue with the right side showing high distortion.
I've isolated cause of distortion to the BA440 op amp module connection.
More than once, I've redone the solder of both the receptacles on the EV11475 motherboard and the pins on the BA440 card. Not just re sweating, but a full clean out of old solder and fresh solder.
It's not the BA440, I've swapped them between channels. Failure always remains on right channel.
Unit performs fine on bench for hours and fails within days of re installation into studio.
In studio the unit is in a console facing upwards
Has anyone here seen this behavior and have a solution?
