does anyone know how to make a meter work in an amplifier the old one burned up before i took owner ship as i have repaired the amp now i want the meter to work i put a meter in the hole now i need to build the circuitry
also the new meter reads microamps 0-50 and volts 0-250 on the scale
ps. or any sites with the info! thanks

Use 1n914 diodes RS has them you can replace the rf choke
with a diode cathode facing the same way as the other diode
the probe is just a wire hook that to a pot about 25k run that
to 10 pf cap or you can use a gimmick cap to your ant jack.
The 25k resistor is your sensitivity adjustment.
