Hello- I am in need of a 0-5 KV DC scaled meter with a 1 mA movement in a 3" round black case. I am building an amplifier control circuit and am using 3" round Weston 301 and 1531 series meters. Or, if anyone has a scale plate 0-5 KV for the Weston 301 series I can use just that as I have the 0-1 mA movements here. Thanks, Byron W5FH
