Default Re: AVO Multimeter survey

I have the Avo 8 Mk II; Serial No. 9840.C.364.D

The 15V battery was replaced with an inverter operating from the D cell, with an on/off switch, too long ago to remember and before I could have contemplated designing such a unit, so I'm wondering was there such a modification published sometime in the 60s?

Looking today I find the BLR121 batteries are readily available at sensible prices. The beauty of using a battery is that no power is used as long as you are not taking a reading on the Ω × 100 range
