The varistor seems to be a protective device for the meter. Try two standard silicon diodes (like 1N4001) in anti-parallel, that should do the trick. I presume the voltage required across the meter for a full reading is below 0.5V. Nikolaus Löwe |

Yes, I know that the varistor is a protective device for the microammeter, and also thought of employing two silicon diodes to replace it. But ... I'm trying to get the varistor in order to preserve the originality of the meter. Thank you for suggesting. Meyer |
