I have some balancing boards that I designed for my series IIIc that I can sell you. Id have to make more, not sure what the lead time would be. I designed a balancing board that has four channels of balance to unbalance using vintage neve line input transformers, but could also be redesigned to use any other line input transformer. It also has four channels of balance to unbalance using burr brown INA134¹s, and eight channels of unbalanced to balanced using burr brown DRV134. This would cover the line inputs, the insert sends/returns, and the direct/group outputs.
But thing that I came across when I was designing the modifications for my series III is that the patch jacks themselves were unbalanced with no contact at tip. Not sure the configuration of the series 1, but it may need more than just the balancing pcbs. I had to replace the patch bay and all the wiring in the console. But that had its benefits as the power looming is miles from where it was, and the patch bay was increased from 28 wide to 32 and now includes mic lines on the patchbay. Let me know if you would be interested in the PCB¹s.

I have a Series 1 that uses card edge connecters and need to address the direct outs and line ins as well as the master outs. What are my options to convert these to balanced? Thanks, Tom
