Now there was two versions.
1) MC had batteries and my patent MC stage
2) MC was a simple OP Amp bodged in after I left the company as the new owner did not want to pay for the use off the patent.
Version 1 after a few year the batteries must be replaced due fatigue.
Version 2 Tony put in the old 741 chip not so good for MC. But there is plenty of replacements to improve the stage.
