I purchased a Solartron 7075 7.5 digit voltmeter from Ebay and decided to make some front panel modifications, firstly to replace the 5-pin input connector with banana sockets, and also to replace the broken handles. Once done I went ahead and performed a partial re-calibration using my own voltage source and HP3458a DMM as a transfer standard.

My Maynuo M9811 has a factory 200W limit, and for fun I thought I'd attempt a 300W upgrade to the M9812 spec!
In this 2nd part video I find a way forward to make the 300W modification.

This is Part 5 of the repair of my Keithley 2001 7.5 digit Multimeter. Picked up quite cheap I was hoping for an in-depth repair.....and it certainly hasn't disappointed so far!
In this video I work on the analog board, getting power to it and making some changes to the pre-regulator AC voltage selection circuits.
